Enum FnAndArgs 

pub enum FnAndArgs {
    Single {
        ext_fn: SmolStr,
        arg: Box<CedarValueJson>,
    },
    Multi {
        ext_fn: SmolStr,
        args: Vec<CedarValueJson>,
    },
}

Structure expected by the __extn escape

Variants

Single

Single-argument function

Fields

ext_fn: SmolStr

Extension constructor function

arg: Box<CedarValueJson>

Argument to that constructor

Multi

Multi-argument function

Fields

ext_fn: SmolStr

Extension constructor function

args: Vec<CedarValueJson>

Arguments to that constructor

Implementations

impl FnAndArgs

pub fn into_expr( self, ctx: impl Fn() -> JsonDeserializationErrorContext + Clone, ) -> Result<RestrictedExpr, JsonDeserializationError>

Convert this FnAndArg into a Cedar “restricted expression” (which will be a call to an extension constructor)

Trait Implementations

impl Clone for FnAndArgs

fn clone(&self) -> FnAndArgs

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FnAndArgs

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FnAndArgs

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FnAndArgs

fn eq(&self, other: &FnAndArgs) -> 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 FnAndArgs

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for FnAndArgs
