[−][src]Struct xterm_js_sys::xterm::BufferNamespace
Represents the terminal's set of buffers.
(This is a duck-typed interface).

Implementations
impl BufferNamespace
[src]
impl BufferNamespace
[src]
pub fn alternate(&self) -> Buffer
[src]
Gets the alternate buffer. This becomes the active buffer when an
application enters this mode via DECSET (CSI ? 4 7 h
).

impl BufferNamespace
[src]
pub fn on_buffer_change(
&self,
listener: &Closure<dyn FnMut(Buffer)>
) -> Disposable
[src]
&self,
listener: &Closure<dyn FnMut(Buffer)>
) -> Disposable
Adds an event listener for when the active buffer changes.
Returns a Disposable
to stop listening.
See attach_buffer_change_event_listener
(if the ext
feature is
enabled) for a friendlier version of this function.
impl BufferNamespace
[src]
pub fn attach_buffer_change_event_listener<F>(
&self,
listener: F
) -> DisposableWrapper<Disposable> where
F: FnMut(Buffer),
F: 'static,
[src]
&self,
listener: F
) -> DisposableWrapper<Disposable> where
F: FnMut(Buffer),
F: 'static,
feature="ext"
only.Attaches an event listener for when the active buffer changes and
returns a DisposableWrapper
that can be dropped to make xterm.js
stop sending the event listener events.
This is sugar for BufferNamespace::on_buffer_change
.
We assume event listener closures are going to be long-lived, so we leak the closure that is produced here!

pub const NULL: JsValue
[src]
pub const UNDEFINED: JsValue
[src]
pub const TRUE: JsValue
[src]
pub const FALSE: JsValue
[src]
pub fn as_f64(&self) -> Option<f64>
[src]
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
[src]
feature="ext"
only.Tests whether this JS value is a JS string.
pub fn as_string(&self) -> Option<String>
[src]
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>
[src]
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
[src]
feature="ext"
only.Tests whether this JS value is null
pub fn is_undefined(&self) -> bool
[src]
feature="ext"
only.Tests whether this JS value is undefined
pub fn is_symbol(&self) -> bool
[src]
feature="ext"
only.Tests whether the type of this JS value is symbol
pub fn is_object(&self) -> bool
[src]
feature="ext"
only.Tests whether typeof self == "object" && self !== null
.
pub fn is_function(&self) -> bool
[src]
feature="ext"
only.Tests whether the type of this JS value is function
.
pub fn is_truthy(&self) -> bool
[src]
feature="ext"
only.Tests whether the value is "truthy".
pub fn is_falsy(&self) -> bool
[src]
feature="ext"
only.Tests whether the value is "falsy".

for the duration of the invocation of the function that has an &Self
parameter. This is required to ensure that the lifetimes don't persist beyond one function call, and so that they remain anonymous. Read more
