[−][src]Trait kernel::hil::time::Ticks
An integer type defining the width of a time value, which allows clients to know when wraparound will occur.
Required methods
pub fn into_usize(self) -> usize
[src]
Converts the type into a usize
, stripping the higher bits
it if it is larger than usize
and filling the higher bits
with 0 if it is smaller than usize
.
pub fn into_u32(self) -> u32
[src]
Converts the type into a u32
, stripping the higher bits
it if it is larger than u32
and filling the higher bits
with 0 if it is smaller than u32
. Included as a simple
helper since Tock uses u32
pervasively and most platforms
are 32 bits.
pub fn wrapping_add(self, other: Self) -> Self
[src]
Add two values, wrapping around on overflow using standard unsigned arithmetic.
pub fn wrapping_sub(self, other: Self) -> Self
[src]
Subtract two values, wrapping around on underflow using standard unsigned arithmetic.
pub fn within_range(self, start: Self, end: Self) -> bool
[src]
Returns whether the value is in the range of [start,
end) using unsigned arithmetic and considering wraparound. It returns
trueif, incrementing from
start, the value will be reached before
end. Put another way, it returns
(self - start) < (end - start)` in
unsigned arithmetic.
pub fn max_value() -> Self
[src]
Returns the maximum value of this type, which should be (2^width)-1.
