Struct PermissionContext 

pub struct PermissionContext {
    domain: Option<PermissionDomain>,
    world: Option<Identifier>,
    custom_contexts: Vec<PermissionRuleContext>,
}

Active runtime context used to evaluate permission rules.

Fields

domain: Option<PermissionDomain>

world: Option<Identifier>

custom_contexts: Vec<PermissionRuleContext>

Implementations

impl PermissionContext

pub fn global() -> Self

Creates a context with no active scopes.

pub fn for_world(world: Identifier) -> Self

Creates a context for a loaded world and its owning domain.

pub fn from_rule_context( rule_context: &PermissionRuleContext, ) -> Result<Self, PermissionRuleContextError>

Builds the active context represented by one rule-side expression.

World namespaces are Steel domain names, matching command-visible world identifiers.

Errors

Returns an error if a custom context value conflicts with another value.

fn append_rule_context( &mut self, rule_context: &PermissionRuleContext, ) -> Result<(), PermissionRuleContextError>

pub fn with_custom_context( self, key: PermissionContextKey, value: impl Into<String>, ) -> Result<Self, PermissionRuleContextError>

Adds one custom active context.

Errors

Returns an error for an empty value or a conflicting value for the same key.

pub fn add_custom_context( &mut self, key: PermissionContextKey, value: impl Into<String>, ) -> Result<(), PermissionRuleContextError>

Adds one custom active context in place.

Errors

Returns an error for an empty value or a conflicting value for the same key.
