Implementations

impl BufferCell

pub fn get_bg_color(&self) -> Color

Gets a cell’s background color number, this differs depending on what the color mode of the cell is:

• Default: This should be 0, representing the default background color (CSI 49 m).
• Palette: This is a number from 0 to 255 of ANSI colors (CSI 4(0-7) m, CSI 10(0-7) m, CSI 48 ; 5 ; 0-255 m).
• RGB: A hex value representing a ‘true color’: 0xRRGGBB (CSI 4 8 ; 2 ; Pi ; Pr ; Pg ; Pb)

impl BufferCell

pub fn get_bg_color_mode(&self) -> u8

Gets the number representation of the background color mode, this can be used to perform quick comparisons of 2 cells to see if they’re the same. Use is_bg_rgb, is_bg_palette, and is_bg_default to check what color mode a cell is.

impl BufferCell

pub fn get_chars(&self) -> Str

The character(s) within the cell. Examples of what this can contain:

• A normal width character
• A wide character (eg. CJK)
• An emoji

impl BufferCell

pub fn get_code(&self) -> u32

Gets the UTF32 codepoint of single characters, if content is a combined string it returns the codepoint of the last character in the string.

impl BufferCell

pub fn get_fg_color(&self) -> Color

Gets a cell’s foreground color number, this differs depending on what the color mode of the cell is:

• Default: This should be 0, representing the default foreground color (CSI 39 m).
• Palette: This is a number from 0 to 255 of ANSI colors (CSI 3(0-7) m, CSI 9(0-7) m, CSI 38 ; 5 ; 0-255 m).
• RGB: A hex value representing a ‘true color’: 0xRRGGBB. (CSI 3 8 ; 2 ; Pi ; Pr ; Pg ; Pb)

impl BufferCell

pub fn get_fg_color_mode(&self) -> u8

Gets the number representation of the foreground color mode, this can be used to perform quick comparisons of 2 cells to see if they’re the same. Use is_fg_rgb, is_fg_palette, and is_fg_default to check what color mode a cell is.

impl BufferCell

pub fn get_width(&self) -> u8

The width of the character. Some examples:

• 1 for most cells.
• 2 for wide character like CJK glyphs.
• 0 for cells immediately following cells with a width of 2.

Methods from Deref<Target = JsValue>

pub const NULL: JsValue

pub const UNDEFINED: JsValue

pub const TRUE: JsValue

pub const FALSE: JsValue

pub fn as_f64(&self) -> Option<f64>

This is supported on feature="ext" only.

Returns the f64 value of this JS value if it's an instance of a number.

If this JS value is not an instance of a number then this returns None.

pub fn is_string(&self) -> bool

This is supported on feature="ext" only.

Tests whether this JS value is a JS string.

pub fn as_string(&self) -> Option<String>

This is supported on feature="ext" only.

If this JS value is a string value, this function copies the JS string value into wasm linear memory, encoded as UTF-8, and returns it as a Rust String.

To avoid the copying and re-encoding, consider the JsString::try_from() function from js-sys instead.

If this JS value is not an instance of a string or if it's not valid utf-8 then this returns None.

UTF-16 vs UTF-8

JavaScript strings in general are encoded as UTF-16, but Rust strings are encoded as UTF-8. This can cause the Rust string to look a bit different than the JS string sometimes. For more details see the documentation about the str type which contains a few caveats about the encodings.

pub fn as_bool(&self) -> Option<bool>

This is supported on feature="ext" only.

Returns the bool value of this JS value if it's an instance of a boolean.

If this JS value is not an instance of a boolean then this returns None.

pub fn is_null(&self) -> bool

This is supported on feature="ext" only.

Tests whether this JS value is null

pub fn is_undefined(&self) -> bool

This is supported on feature="ext" only.

Tests whether this JS value is undefined

pub fn is_symbol(&self) -> bool

This is supported on feature="ext" only.

Tests whether the type of this JS value is symbol

pub fn is_object(&self) -> bool

This is supported on feature="ext" only.

Tests whether typeof self == "object" && self !== null.

pub fn is_function(&self) -> bool

This is supported on feature="ext" only.

Tests whether the type of this JS value is function.

pub fn is_truthy(&self) -> bool

This is supported on feature="ext" only.

Tests whether the value is "truthy".

pub fn is_falsy(&self) -> bool

This is supported on feature="ext" only.

Tests whether the value is "falsy".
