pub struct EnableCommand { /* private fields */ }Debugger and Runtime only.Expand description
Enables debugger for the given page. Clients should not assume that the debugging has been enabled until the result for this command is received.
Implementations§
Source§impl EnableCommand
impl EnableCommand
pub fn new(max_scripts_cache_size: Option<f64>) -> Self
Sourcepub fn max_scripts_cache_size(&self) -> Option<&f64>
Available on crate feature experimental only.
pub fn max_scripts_cache_size(&self) -> Option<&f64>
experimental only.The maximum size in bytes of collected scripts (not referenced by other heap objects) the debugger can hold. Puts no limit if paramter is omitted.
Methods from Deref<Target = Option<f64>>§
1.0.0 · Sourcepub fn as_ref(&self) -> Option<&T>
pub fn as_ref(&self) -> Option<&T>
Converts from &Option<T> to Option<&T>.
§Examples
Calculates the length of an Option<String> as an Option<usize>
without moving the String. The map method takes the self argument by value,
consuming the original, so this technique uses as_ref to first take an Option to a
reference to the value inside the original.
let text: Option<String> = Some("Hello, world!".to_string());
// First, cast `Option<String>` to `Option<&String>` with `as_ref`,
// then consume *that* with `map`, leaving `text` on the stack.
let text_length: Option<usize> = text.as_ref().map(|s| s.len());
println!("still can print text: {text:?}");1.75.0 · Sourcepub fn as_slice(&self) -> &[T]
pub fn as_slice(&self) -> &[T]
Returns a slice of the contained value, if any. If this is None, an
empty slice is returned. This can be useful to have a single type of
iterator over an Option or slice.
Note: Should you have an Option<&T> and wish to get a slice of T,
you can unpack it via opt.map_or(&[], std::slice::from_ref).
§Examples
assert_eq!(
[Some(1234).as_slice(), None.as_slice()],
[&[1234][..], &[][..]],
);The inverse of this function is (discounting
borrowing) [_]::first:
for i in [Some(1234_u16), None] {
assert_eq!(i.as_ref(), i.as_slice().first());
}1.40.0 · Sourcepub fn as_deref(&self) -> Option<&<T as Deref>::Target>where
T: Deref,
pub fn as_deref(&self) -> Option<&<T as Deref>::Target>where
T: Deref,
Converts from Option<T> (or &Option<T>) to Option<&T::Target>.
Leaves the original Option in-place, creating a new one with a reference
to the original one, additionally coercing the contents via Deref.
§Examples
let x: Option<String> = Some("hey".to_owned());
assert_eq!(x.as_deref(), Some("hey"));
let x: Option<String> = None;
assert_eq!(x.as_deref(), None);Trait Implementations§
