Struct scale_typegen::typegen::settings::substitutes::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() -> Self

Creates a new TypeSubstitutes with no default derives.

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: &PathSegments) -> bool

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

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

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

pub fn iter(&self) -> impl Iterator<Item = (&PathSegments, &Substitute)>

Returns an iterator over all substitutes.
