Struct Trace 

pub struct Trace<const S: bool, T: TraceValue, const N: usize>
where
    TDesc<S>: TArch,
{ /* private fields */ }

A Trace can be used to trace the execution of some code, from an start point through a series of intermediate points. The delta for each step can be recorded.

The ‘start’ method is called first; at each completed step the ‘next’ method is called. At the end (after no more than ‘N’ steps!) the deltas for each step of the trace can be recovered with the ‘trace’ method.

A Trace can be generated for any N, for T in u8, u16, u32, u64, u128 and usize

Implementations

impl<const S: bool, T, const N: usize> Trace<S, T, N>

where TDesc<S>: TArch, T: TraceValue,

pub fn clear(&mut self)

Clear the timer and trace

pub fn start(&mut self)

Record the ticks on start to a region-to-time

Up to N invocations of ‘next’ afterwards will store individual deltas in the trace

pub fn next(&mut self)

Calculate the delta since the last ‘start’ or ‘next’, and store it in the next trace slot

If this is invoked more than N times after a start then no work is done, as there is no space to store the time in the internal trace

pub fn trace(&self) -> &[T; N]

Return the current trace

Trait Implementations
