Struct chrome_remote_interface_model::emulation::SetVirtualTimePolicyReturn [−][src]
Emulation

and Page

and experimental
only.Turns on virtual time for all frames (replacing real-time with a synthetic time source) and sets the current virtual time policy. Note this supersedes any previous time budget.
Implementations
impl SetVirtualTimePolicyReturn
[src]
pub fn new(virtual_time_ticks_base: f64) -> Self
[src]
pub fn virtual_time_ticks_base(&self) -> f64
[src]
Absolute timestamp at which virtual time was first enabled (up time in milliseconds).

pub fn as_ne_bytes(&self) -> &[u8; 8]
[src]
num_as_ne_bytes
)Return the memory representation of this floating point number as a byte array in native byte order.
to_ne_bytes
should be preferred over this whenever possible.
Examples
#![feature(num_as_ne_bytes)] let num = 12.5f64; let bytes = num.as_ne_bytes(); assert_eq!( bytes, if cfg!(target_endian = "big") { &[0x40, 0x29, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00] } else { &[0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x29, 0x40] } );
pub fn total_cmp(&self, other: &f64) -> Ordering
[src]
total_cmp
)Returns an ordering between self and other values. Unlike the standard partial comparison between floating point numbers, this comparison always produces an ordering in accordance to the totalOrder predicate as defined in IEEE 754 (2008 revision) floating point standard. The values are ordered in following order:
- Negative quiet NaN
- Negative signaling NaN
- Negative infinity
- Negative numbers
- Negative subnormal numbers
- Negative zero
- Positive zero
- Positive subnormal numbers
- Positive numbers
- Positive infinity
- Positive signaling NaN
- Positive quiet NaN
Note that this function does not always agree with the PartialOrd
and PartialEq
implementations of f64
. In particular, they regard
negative and positive zero as equal, while total_cmp
doesn't.
Example
#![feature(total_cmp)] struct GoodBoy { name: String, weight: f64, } let mut bois = vec![ GoodBoy { name: "Pucci".to_owned(), weight: 0.1 }, GoodBoy { name: "Woofer".to_owned(), weight: 99.0 }, GoodBoy { name: "Yapper".to_owned(), weight: 10.0 }, GoodBoy { name: "Chonk".to_owned(), weight: f64::INFINITY }, GoodBoy { name: "Abs. Unit".to_owned(), weight: f64::NAN }, GoodBoy { name: "Floaty".to_owned(), weight: -5.0 }, ]; bois.sort_by(|a, b| a.weight.total_cmp(&b.weight));
