Struct xterm_js_sys::xterm::BufferLine

#[repr(transparent)]pub struct BufferLine {
    obj: JsValue,
}

Represents a line in the terminal’s buffer.

(This is a duck-typed interface).

Fields

obj: JsValue

Implementations

impl BufferLine

pub fn is_wrapped(&self) -> bool

Whether the line is wrapped from the previous line.

impl BufferLine

pub fn length(&self) -> u16

The length of the line.

All calls to BufferLine::get_cell beyond the length will result in None.

impl BufferLine

pub fn get_cell(&self, cell: Option<BufferCell>) -> Option<BufferCell>

Gets a cell from the line, or None if the line index does not exist.

Note that the result of this function should be used immediately after calling as when the terminal updates it could lead to unexpected behavior.

Takes:

• x: The character index to get.
• cell: Optional cell object to load data into for performance reasons. This is mainly useful when every cell in the buffer is being looped over to avoid creating new objects for every cell.

impl BufferLine

pub fn translate_to_string(
    &self,
    trim_right: Option<bool>,
    start_column: Option<u16>,
    end_column: Option<u16>
) -> Str

Gets the line as a string. Note that this is gets only the string for the line, not taking BufferLine::is_wrapped into account.

Takes:

• trim_right: Whether to trim any whitespace at the right of the line.
• start_column: The column to start from (inclusive).
• end_column: The column to end at (exclusive).

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".
