Enum UserFuncName

pub enum UserFuncName {
    User(UserExternalName),
    Testcase(TestcaseName),
}

An explicit name for a user-defined function, be it defined in code or in CLIF text.

This is used both for naming a function (for debugging purposes) and for declaring external functions. In the latter case, this becomes an ExternalName, which gets embedded in relocations later, etc.

Variants

User(UserExternalName)

A user-defined name, with semantics left to the user.

Testcase(TestcaseName)

A name for a test case, mostly intended for Cranelift testing.

Implementations

impl UserFuncName

pub fn testcase<T: AsRef<[u8]>>(v: T) -> Self

Creates a new external name from a sequence of bytes. Caller is expected to guarantee bytes are only ascii alphanumeric or _.

pub fn user(namespace: u32, index: u32) -> Self

Create a new external name from a user-defined external function reference.

pub fn get_user(&self) -> Option<&UserExternalName>

Get a UserExternalName if this is a user-defined name.

Trait Implementations

impl Clone for UserFuncName

fn clone(&self) -> UserFuncName

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UserFuncName

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

Formats the value using the given formatter.

impl Default for UserFuncName

fn default() -> Self

Returns the “default value” for a type.

impl Display for UserFuncName

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

Formats the value using the given formatter.

impl Hash for UserFuncName

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for UserFuncName

fn eq(&self, other: &UserFuncName) -> 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.
