Struct HostOpenPlan 

pub struct HostOpenPlan { /* private fields */ }

Resolved plan describing how a device would be opened.

Names the backend, device, the effect kinds the open performs, and the capabilities the open requires.

Implementations

impl HostOpenPlan

pub fn new( backend: Symbol, device: Symbol, effect_kinds: Vec<Symbol>, requires: Vec<CapabilityName>, ) -> Self

Builds an open plan from resolved backend, device, effects, and required capabilities.

pub fn backend(&self) -> &Symbol

Returns the backend that would perform the open.

pub fn device(&self) -> &Symbol

Returns the device that would be opened.

pub fn effect_kinds(&self) -> &[Symbol]

Returns the effect kinds the open performs.

pub fn requires(&self) -> &[CapabilityName]

Returns the capabilities the open requires.

pub fn enforce(&self, cx: &mut Cx) -> Result<()>

Enforces the plan’s capabilities and records every declared device effect in the supplied context before a host stream is opened.
