pub struct OutputToString { /* private fields */ }

Helper structure to help maintain an indentation level when printing source, modeled after the support in wit-bindgen-core. Indentation is set to two spaces.

fn default() -> OutputToString

Returns the “default value” for a type.

impl Display for OutputToString

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

Formats the value using the given formatter.

impl From<OutputToString> for String

fn from(output: OutputToString) -> String

Converts to this type from the input type.

impl Output for OutputToString

fn push_str(&mut self, src: &str)

Push a string slice into a buffer or an output.

fn indent_if_needed(&mut self) -> bool

Set the appropriate indentation.

fn indent_start(&mut self)

fn keyword(&mut self, src: &str)

A keyword is added. Keywords are hardcoded strings from [a-z], but can start with @ when printing a Feature Gate

fn ty(&mut self, src: &str, _kind: TypeKind)

A type is added.

fn param(&mut self, src: &str)

A parameter name of a function, record or a named return is added.

fn case(&mut self, src: &str)

A case belonging to a variant, enum or flags is added.

fn generic_args_start(&mut self)

Generic argument section starts. In WIT this represents the < character.

fn generic_args_end(&mut self)

Generic argument section ends. In WIT this represents the ‘>’ character.
