Struct BeamTypeCtx 

pub struct BeamTypeCtx { /* private fields */ }

A lightweight type-checking context for BEAM expressions.

This performs best-effort type inference for documentation purposes.

Implementations

impl BeamTypeCtx

pub fn new() -> Self

Create an empty type context.

pub fn bind(&mut self, var: impl Into<String>, ty: BeamType)

Bind a variable to a type.

pub fn lookup(&self, var: &str) -> Option<&BeamType>

Look up the type of a variable.

pub fn register_fun( &mut self, name: impl Into<String>, params: Vec<BeamType>, ret: BeamType, )

Register a function’s type signature.

pub fn infer(&self, expr: &BeamExpr) -> BeamType

Infer the type of a BeamExpr (returns Any when unknown).

pub fn merge(&self, other: &BeamTypeCtx) -> BeamTypeCtx

Merge another context (e.g., from two branches).

Trait Implementations

impl Clone for BeamTypeCtx

fn clone(&self) -> BeamTypeCtx

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BeamTypeCtx

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

Formats the value using the given formatter.

impl Default for BeamTypeCtx

fn default() -> BeamTypeCtx

Returns the “default value” for a type.
