source · [−]

pub struct VarRef { /* private fields */ }

Expand description

Represents a reference to a variable (which doesn’t have to exist).

Implementations

source

impl VarRef

source

pub fn new<T: Into<String>>(name: T, ref_type: VarType) -> Self

Creates a new reference to the variable with name and the optional vtype type.

source

pub fn into_unannotated_string(self) -> Result<String, Error>

Transforms this reference into an unannotated name.

This is only valid for references that have no annotations in them.

source

pub fn name(&self) -> &str

Returns the name of this reference, without any type annotations.

source

pub fn qualify(self, ref_type: VarType) -> Self

Adds the type annotation ref_type to this reference.

Assumes that the current annotation for this reference is Auto and that the given annotation is not.

source

pub fn ref_type(&self) -> VarType

Returns the type of this reference.

source

pub fn accepts(&self, other: VarType) -> bool

Returns true if this reference is compatible with the given type.
