Implementations

Gets the new number of columns.

impl ResizeEventData

pub fn rows(&self) -> u16

Gets the new number of rows.

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".
