Struct subxt_codegen::TypeSubstitutes

pub struct TypeSubstitutes { /* private fields */ }

A map of type substitutes. We match on the paths to generated types in order to figure out when to swap said type with some provided substitute.

Implementations

impl TypeSubstitutes

pub fn new(crate_path: &CratePath) -> Self

Create a new set of type substitutes with some default substitutions in place.

pub fn insert( &mut self, source: Path, target: AbsolutePath ) -> Result<(), TypeSubstitutionError>

Insert the given substitution, overwriting any other with the same path.

pub fn insert_if_not_exists( &mut self, source: Path, target: AbsolutePath ) -> Result<(), TypeSubstitutionError>

Only insert the given substitution if a substitution at that path doesn’t already exist.

pub fn extend( &mut self, elems: impl IntoIterator<Item = (Path, AbsolutePath)> ) -> Result<(), TypeSubstitutionError>

Add a bunch of source to target type substitutions.

pub fn contains(&self, path: impl Into<PathSegments>) -> bool

Given a source type path, return whether a substitute exists for it.

pub fn for_path_with_params( &self, path: impl Into<PathSegments>, params: &[TypePath] ) -> Option<TypePathType>

Given a source type path and the resolved, supplied type parameters, return a new path and optionally overwritten type parameters.

impl Debug for TypeSubstitutes

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

Formats the value using the given formatter.
