Enum TypeExpr 

pub enum TypeExpr<'a> {
    Simple(&'a str, Vec<TypeExprParam<'a>>, bool),
    UserDefined(&'a str, Vec<TypeExprParam<'a>>, bool),
    TypeVariable(u32, bool),
    Func(Vec<TypeExprParam<'a>>, Box<TypeExpr<'a>>, bool),
}

Available on crate feature parse only.

A parsed type expression from a type string, with lifetime tied to the original string.

This represents the syntactic structure only - type names are not validated. Convert to Type for semantic validation.

Variants

Simple(&'a str, Vec<TypeExprParam<'a>>, bool)

A type without the u! prefix (expected to be a builtin like i32, List, etc.)

Contains: (name, parameters, nullable)

UserDefined(&'a str, Vec<TypeExprParam<'a>>, bool)

A user-defined extension type with the u! prefix (e.g., u!geometry)

Contains: (name without u! prefix, parameters, nullable)

TypeVariable(u32, bool)

Type variable (e.g., any1, any2)

Contains: (variable id, nullable)

Func(Vec<TypeExprParam<'a>>, Box<TypeExpr<'a>>, bool)

A function type (e.g., func<i32 -> i64>)

Contains: (parameters, return type, nullable)

Implementations

impl<'a> TypeExpr<'a>

pub fn parse(type_str: &'a str) -> Result<Self, TypeParseError>

Parse a type string into a TypeExpr.

pub fn visit_references<F>(&self, on_ext: &mut F)

where F: FnMut(&str),

Visit all extension type references contained in a parsed type, calling on_ext for each encountered extension name (including named extension forms).
