pub struct WitPrinter<O: Output = OutputToString> {
    pub output: O,
    /* private fields */
}

A utility for printing WebAssembly interface definitions to a string.

Fields

output: O

Visitor that holds the WIT document being printed.

Implementations

impl<O: Output> WitPrinter<O>

pub fn new(output: O) -> Self

Craete new instance.

pub fn print( &mut self, resolve: &Resolve, pkg: PackageId, nested: &[PackageId], ) -> Result<()>

Prints the specified pkg which is located in resolve to O.

The nested list of packages are other packages to include at the end of the output in package ... { ... } syntax.

pub fn emit_docs(&mut self, enabled: bool) -> &mut Self

Configure whether doc comments will be printed.

Defaults to true.

pub fn print_package( &mut self, resolve: &Resolve, pkg: PackageId, is_main: bool, ) -> Result<()>

Prints the specified pkg.

If is_main is not set, nested package notation is used.

pub fn print_package_outer(&mut self, pkg: &Package) -> Result<()>

Print the specified package without its content. Does not print the semicolon nor starts the indentation.

pub fn print_interface_outer( &mut self, resolve: &Resolve, id: InterfaceId, name: &str, ) -> Result<()>

Print the given WebAssembly interface without its content. Does not print the semicolon nor starts the indentation.

pub fn print_interface( &mut self, resolve: &Resolve, id: InterfaceId, ) -> Result<()>

Print the inner content of a given WebAssembly interface.

pub fn print_types<'a>( &mut self, resolve: &Resolve, owner: TypeOwner, types: impl Iterator<Item = (&'a str, TypeId)>, resource_funcs: &HashMap<TypeId, Vec<&Function>>, ) -> Result<()>

Print types of an interface.

pub fn print_type_name(&mut self, resolve: &Resolve, ty: &Type) -> Result<()>

Print the name of type ty.

impl Default for WitPrinter

fn default() -> Self

Returns the “default value” for a type.
