Struct GraphLimits 

pub struct GraphLimits { /* private fields */ }

Hard bounded retrieval limits accepted by repository graph consumers.

Implementations

impl GraphLimits

pub const MAX_ROWS: u32 = 10_000

Absolute row ceiling for any one graph request.

pub const MAX_OCCURRENCES: u32 = 1_024

Absolute occurrence ceiling for any one logical relation.

pub const MAX_DEPTH: u32 = 64

Absolute traversal-depth ceiling.

pub const MAX_OUTPUT_BYTES: u32

Absolute encoded-output ceiling.

pub fn new( rows: u32, occurrences: u32, depth: u32, output_bytes: u32, ) -> Result<Self, GraphContractError>

Validate result-defining hard limits.

Errors

Returns an error for zero values or values above absolute ceilings.

pub const fn rows(self) -> u32

Return the logical-row limit.

pub const fn occurrences(self) -> u32

Return the per-relation occurrence limit.

pub const fn depth(self) -> u32

Return the traversal-depth limit.

pub const fn output_bytes(self) -> u32

Return the encoded-output byte limit.

Trait Implementations

impl Clone for GraphLimits

fn clone(&self) -> GraphLimits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphLimits

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GraphLimits

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for GraphLimits

fn eq(&self, other: &GraphLimits) -> 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.

impl Serialize for GraphLimits

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
