Struct SelectionBuffers 

pub struct SelectionBuffers<const WANTS: usize, const OBJECTS: usize, const READ: usize, const PARSE: usize> { /* private fields */ }

Fixed-capacity backing storage for one independent selected-fetch session. All capacities are explicit const parameters; construction allocates nothing. Keep separate values for overlapping responses. Only the borrowed descriptor reaches the protocol encoder, so applications may also keep their own arrays and construct SelectionStorage directly.

Implementations

impl<const WANTS: usize, const OBJECTS: usize, const READ: usize, const PARSE: usize> SelectionBuffers<WANTS, OBJECTS, READ, PARSE>

pub const fn new() -> Self

pub fn storage(&mut self, graph_read_limit: u64) -> SelectionStorage<'_>

Borrow a fresh request descriptor. Traversal resets the work arrays; no clearing or reallocation is needed between successful/failed requests.

pub const fn want_capacity(&self) -> usize

pub const fn object_capacity(&self) -> usize

pub const fn read_capacity(&self) -> usize

pub const fn parse_capacity(&self) -> usize

pub const fn storage_bytes(&self) -> usize

Bytes owned by this value, including metadata and alignment padding.

Trait Implementations

impl<const WANTS: usize, const OBJECTS: usize, const READ: usize, const PARSE: usize> Default for SelectionBuffers<WANTS, OBJECTS, READ, PARSE>

fn default() -> Self

Returns the “default value” for a type.
