Struct CsCoord 

pub struct CsCoord { /* private fields */ }

Coordination that uses a critical section to perform coordination operations

The critical section is only taken for a short time to obtain or release grants, not for the entire duration of the grant.

Implementations

impl CsCoord

pub const fn new() -> Self

Create a new critical-section based coordination

Trait Implementations

impl ConstInit for CsCoord

const INIT: Self

The default value of this type

impl Coord for CsCoord

fn reset(&self)

Reset all values back to the initial empty state

fn grant_max_remaining( &self, capacity: usize, sz: usize, ) -> Result<(usize, usize), WriteGrantError>

Obtain a non-zero length grant UP TO sz of available writing space, e.g. 0 < len <= sz.

fn grant_exact( &self, capacity: usize, sz: usize, ) -> Result<usize, WriteGrantError>

Obtain a grant of EXACTLY sz bytes.

fn read(&self) -> Result<(usize, usize), ReadGrantError>

Attempt to obtain a read grant.

fn commit_inner(&self, capacity: usize, grant_len: usize, used: usize)

Make used bytes available

fn release_inner(&self, used: usize)

Mark used bytes as available for writing

impl Default for CsCoord

fn default() -> Self

Returns the “default value” for a type.
