Struct FunctionMetadata

pub struct FunctionMetadata<'a> {
    pub signature: UniqueSignatureIndex,
    pub name: Option<&'a str>,
}

Information about the corresponding function.

This is split from but closely related to a FunctionSpec. The distinction is largely for serialization/deserialization simplicity, as FunctionSpec contains fields that need cooperation from a loader, with manual layout and serialization as a result. FunctionMetadata is the remainder of fields that can be automatically serialized/deserialied and are small enough copying isn’t a large concern.

Fields

signature: UniqueSignatureIndex

name: Option<&'a str>

the “name” field is some human-friendly name, not necessarily the same as used to reach this function (through an export, for example), and may not even indicate that a function is exported at all. TODO: at some point when possible, this field ought to be set from the names section of a wasm module. At the moment that information is lost at parse time.

Trait Implementations

impl<'a> Debug for FunctionMetadata<'a>

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

Formats the value using the given formatter.

impl<'de: 'a, 'a> Deserialize<'de> for FunctionMetadata<'a>

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> Serialize for FunctionMetadata<'a>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
