Struct PermissionMetadataSet 

pub struct PermissionMetadataSet {
    entries: Vec<PermissionMetadataEntry>,
    sources: Vec<PermissionResolutionSource>,
}

A flat effective permission metadata set.

Fields

entries: Vec<PermissionMetadataEntry>

sources: Vec<PermissionResolutionSource>

Implementations

impl PermissionMetadataSet

pub const fn new() -> Self

Creates an empty metadata set.

pub fn from_entries( entries: impl IntoIterator<Item = PermissionMetadataEntry>, ) -> Self

Creates a subject metadata set from entries.

pub fn entries(&self) -> &[PermissionMetadataEntry]

Returns all entries in insertion order.

pub const fn is_empty(&self) -> bool

Returns whether the set contains no entries.

pub fn push(&mut self, entry: PermissionMetadataEntry)

Adds one subject metadata rule.

pub fn set(&mut self, key: Identifier, value: PermissionMetadataValue)

Sets one exact global value, replacing any previous exact value.

pub fn set_in( &mut self, key: Identifier, context: PermissionRuleContext, value: PermissionMetadataValue, )

Sets one exact contextual value, replacing any previous exact value.

pub fn unset(&mut self, key: &Identifier) -> bool

Removes one exact global value.

pub fn unset_in( &mut self, key: &Identifier, context: &PermissionRuleContext, ) -> bool

Removes one exact contextual value.

pub fn resolve(&self, key: &Identifier) -> Option<&PermissionMetadataValue>

Resolves one value in the global context.

pub fn resolve_in( &self, key: &Identifier, context: &PermissionContext, ) -> Option<&PermissionMetadataValue>

Resolves one value in an active permission context.

More-specific contexts win. Ties prefer subject metadata, then group priority, then the final insertion order for deterministic resolution.

pub fn resolve_detailed( &self, key: &Identifier, ) -> Option<PermissionMetadataResolution>

Resolves one global value and returns the winning rule.

pub fn resolve_in_detailed( &self, key: &Identifier, context: &PermissionContext, ) -> Option<PermissionMetadataResolution>

Resolves one contextual value and returns the winning rule.

pub(super) fn push_group( &mut self, entry: PermissionMetadataEntry, group: &str, group_priority: i32, )

fn push_with_source( &mut self, entry: PermissionMetadataEntry, source: PermissionResolutionSource, )

fn retain_entries(&mut self, keep: impl FnMut(&PermissionMetadataEntry) -> bool)

fn best_candidate( &self, key: &Identifier, context: &PermissionContext, ) -> Option<PermissionMetadataCandidate>

fn resolution( &self, candidate: PermissionMetadataCandidate, ) -> PermissionMetadataResolution
