Implementations§

Source§

impl RepositoryGraphReadBudget

Source

pub const MAX_REQUESTED_ROWS: u32 = GraphLimits::MAX_ROWS

Absolute compact-key or purpose-path request ceiling for one batch.

Source

pub const MAX_RETURNED_ROWS: u32 = GraphLimits::MAX_ROWS

Absolute reconstructed-row ceiling for one batch.

Source

pub const MAX_DECODED_BYTES: u64

Absolute decoded payload ceiling for one hydration batch.

Source

pub const MAX_HYDRATED_ENTITIES: u32

Absolute unique-entity ceiling including one adjacency sentinel.

Source

pub const MAX_HYDRATED_PATHS: u32

Absolute unique purpose-owner path ceiling for one hydration batch.

Source

pub fn new( requested_rows: u32, returned_rows: u32, decoded_bytes: u64, hydrated_entities: u32, hydrated_paths: u32, ) -> Result<Self, GraphContractError>

Construct one bounded repository-graph read envelope.

§Errors

Returns an error when a limit is zero or above its absolute batch ceiling.

pub const fn requested_rows(self) -> u32

Maximum input keys, frontier selectors, or purpose-owner paths.

Source

pub const fn returned_rows(self) -> u32

Maximum fully reconstructed rows.

Source

pub const fn decoded_bytes(self) -> u64

Maximum decoded raw payload bytes.

Source

pub const fn hydrated_entities(self) -> u32
