Struct Generator 

pub struct Generator { /* private fields */ }

Generator is a main point of flapigen. It expands rust macroses and generates not rust code. It designed to use inside build.rs.

Implementations

impl Generator

pub fn new(config: LanguageConfig) -> Generator

pub fn with_pointer_target_width(self, pointer_target_width: usize) -> Self

By default we get pointer_target_width via cargo (more exactly CARGO_CFG_TARGET_POINTER_WIDTH), but you can change default value via this method

pub fn rustfmt_bindings(self, doit: bool) -> Self

Set whether rustfmt should format the generated bindings.

pub fn remove_not_generated_files_from_output_directory( self, doit: bool, ) -> Self

If true removes not generated by flapigen files from output directory, suitable for removing obsolete files. Warning! May remove your files if turn on, so by default false

pub fn merge_type_map(self, id_of_code: &str, code: &str) -> Self

Add new foreign langauge type <-> Rust mapping

pub fn register_class_attribute_callback<F>( self, attr_name: &str, cb: F, ) -> Self

where F: Fn(&mut Vec<u8>, &str) + 'static,

Register callback to extend/modify class, if foreign_class has #[derive(attr_name)] then after foreign code generation cb would be called, with full code of module, plus class name

pub fn register_enum_attribute_callback<F>(self, attr_name: &str, cb: F) -> Self

where F: Fn(&mut Vec<u8>, &str) + 'static,

Register callback to extend/modify enum, if foreign_enum has #[derive(attr_name)] then after foreign code generation cb would be called, with full code of module, plus enum name

pub fn register_method_attribute_callback<F>( self, attr_name: &str, cb: F, ) -> Self

where F: Fn(&mut Vec<u8>, MethodInfo<'_>) + 'static,

Register callback to extend/modify method of class, if fn inside foreign_class has attribute, then after foreign code generation cb would be called with full code of moulde, plus class name, plus method name

pub fn expand<S, D>(self, crate_name: &str, src: S, dst: D)

where S: AsRef<Path>, D: AsRef<Path>,

process src and save result of macro expansion to dst

Panics

Panics on error

pub fn expand_many<S, D>(self, crate_name: &str, srcs: &[S], dst: D)

where S: AsRef<Path>, D: AsRef<Path>,

process srcs and save result of macro expansion to dst
