Struct starlark::values::structs::StructOf

pub struct StructOf<'v, V: UnpackValue<'v>> { /* private fields */ }

Like ValueOf, but only validates value types; does not construct or store a map.

Implementations

impl<'v, V: UnpackValue<'v>> StructOf<'v, V>

pub fn to_value(&self) -> Value<'v>

Get the actual value this StructOf wraps.

pub fn to_map(&self) -> SmallMap<StringValue<'v>, V>

Collect field structs.

Trait Implementations

impl<'v, V: Debug + UnpackValue<'v>> Debug for StructOf<'v, V>

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

Formats the value using the given formatter.

impl<'v, V: UnpackValue<'v>> StarlarkTypeRepr for StructOf<'v, V>

fn starlark_type_repr() -> Ty

The representation of a type that a user would use verbatim in starlark type annotations

impl<'v, V: UnpackValue<'v>> UnpackValue<'v> for StructOf<'v, V>

fn expected() -> String

Description of values acceptable by unpack_value, e. g. list or str.

fn unpack_value(value: Value<'v>) -> Option<StructOf<'v, V>>

Given a Value, try and unpack it into the given type, which may involve some element of conversion.

fn unpack_value_err(value: Value<'v>) -> Result<Self>

Unpack a value, but return error instead of None if unpacking fails.

fn unpack_param(value: Value<'v>) -> Result<Self>

Unpack value, but instead of None return error about incorrect argument type.

fn unpack_named_param(value: Value<'v>, param_name: &str) -> Result<Self>

Unpack value, but instead of None return error about incorrect named argument type.
