Struct ClaimPattern 

pub struct ClaimPattern {
    pub subject: Option<Ref>,
    pub predicate: Option<Symbol>,
    pub object: Option<Ref>,
    pub include_revoked: bool,
}

Query pattern matched against stored Claims; None fields are wildcards.

Fields

subject: Option<Ref>

Subject to match, or any subject when None.

predicate: Option<Symbol>

Predicate to match, or any predicate when None.

object: Option<Ref>

Object to match, or any object when None.

include_revoked: bool

Whether revoked claims are included in results.

Implementations

impl ClaimPattern

pub fn any() -> Self

Returns a pattern that matches every claim (all fields wildcard).

pub fn exact(subject: Ref, predicate: Symbol, object: Ref) -> Self

Returns a pattern fixing subject, predicate, and object exactly.

pub fn include_revoked(self) -> Self

Returns the pattern with revoked claims included in results.

Trait Implementations

impl Clone for ClaimPattern

fn clone(&self) -> ClaimPattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClaimPattern

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

Formats the value using the given formatter.

impl Default for ClaimPattern

fn default() -> ClaimPattern

Returns the “default value” for a type.

impl Eq for ClaimPattern

impl PartialEq for ClaimPattern

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