Enum BufferStrategyKind 

#[repr(u8)]
pub enum BufferStrategyKind {
    CallerAllocated = 0,
    PluginAllocated = 1,
    Arena = 2,
}

Buffer management strategy for an interface.

Selected per-trait via #[plugin_interface(buffer = ...)]. Determines the FFI function pointer signatures in the vtable.

Variants

CallerAllocated = 0

Host allocates output buffer; plugin writes into it. Returns -1 with needed size if buffer is too small.

PluginAllocated = 1

Plugin allocates output; host frees via PluginDescriptor::free_buffer.

Arena = 2

Host provides a pre-allocated arena; plugin writes into it. Data is valid only until the next call.

Trait Implementations

impl Clone for BufferStrategyKind

fn clone(&self) -> BufferStrategyKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BufferStrategyKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for BufferStrategyKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for BufferStrategyKind

fn eq(&self, other: &BufferStrategyKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
