Implementors of the Backend trait can be used as a backend to the compiler in order to create bindings for other frameworks and languages than the default backend.

Required Associated Types

type Config: Sized + Default + Debug

Required Associated Constants

const FILE_EXTENSION: &'static str

File extension that should be used for output file containing the generated bindings. For example: .ts for Typescript, .rs for Rasn bindings.

Required Methods

fn generate_module( &self, top_level_declarations: Vec<ToplevelDefinition> ) -> Result<GeneratedModule, GeneratorError>

generates bindings for an ASN.1 module

Params

• top_level_declarations vector of [TopLevelDeclaration]s that are defined in the ASN.1 module

fn generate(&self, tld: ToplevelDefinition) -> Result<String, GeneratorError>

generates bindings for a single ASN.1 item

Params

• tld [TopLevelDeclaration] for which the bindings should be generated

fn config(&self) -> &Self::Config

Returns a reference to the backend’s config

fn from_config(config: Self::Config) -> Self

Creates a backend from its config

Provided Methods

fn format_bindings(bindings: &str) -> Result<String, Box<dyn Error>>

Formats the bindings using the language- or framework-specific linters. For example, the Rust backend uses rustfmt for formatting bindings.

Object Safety

This trait is not object safe.
