WriterRegion

Struct WriterRegion 

Source
pub struct WriterRegion<M> { /* private fields */ }
Expand description

Mapping-lifetime owner that prevents duplicate safe writer binding.

Implementations§

Source§

impl<M: SoleWriterMapping> WriterRegion<M>

Source

pub fn new( mapping: M, layout: ValidatedRegionLayout, topology: RegionSetLayout, ) -> Result<Self, (M, BindingError)>

Consumes a platform-minted unique writer witness.

On rejection, returns the witness alongside the error so the caller recovers the mapping instead of losing it.

Source

pub fn into_mapping(self) -> M

Releases the binding and returns the owned mapping witness.

Source

pub fn slot(&mut self, slot: u32) -> Result<WriterSlot<'_>, BindingError>

Exclusively binds one checked producer slot.

Source

pub fn publish( &mut self, slot: u32, sequence: u64, acknowledgement: Option<AcknowledgementObservation>, payload: &[u8], ) -> Result<(), BindingError>

Copies an owned caller payload into a checked slot and publishes it.

Source

pub fn acknowledgement( &mut self, target: RoleId, slot: u32, ) -> Result<AcknowledgementWriter<'_>, BindingError>

Exclusively binds one checked acknowledgement cell.
