Struct CodegenBuf

Source
pub struct CodegenBuf {
    inner: String,
    level: usize,
}
Expand description

A code generation buffer.

A CodegenBuf provides a string-based API for generating Rust code. Its value is in the various function it provides to automatically manage indentation.

Implementations§

Source§

impl CodegenBuf

Source

pub fn new() -> CodegenBuf

Creates a new code generation buffer.

Source

pub fn into_string(self) -> String

Consumes the buffer, returning its contents.

Source

pub fn write<S>(&mut self, s: S)
where S: AsRef<str>,

Writes a string into the buffer directly.

Source

pub fn writeln<S>(&mut self, s: S)
where S: AsRef<str>,

Writes a line into the buffer at the current indentation level.

Specifically, the method writes (4 * indentation level) spaces into the buffer, followed by s, followed by a newline character.

Source

pub fn start_line(&mut self)

Starts a new line.

Specifically, the method writes (4 * indentation level) spaces into the buffer.

Source

pub fn end_line(&mut self)

Ends the current line.

Specifically, the method writes a newline character into the buffer.

Source

pub fn write_block<S, F>(&mut self, s: S, f: F)
where S: AsRef<str>, F: FnOnce(&mut Self),

Writes a new indented block.

Specifically, if s is empty, the method writes the line { into the buffer; otherwise writes the line s { into the buffer at the current indentation level. Then it increments the buffer’s indentation level, runs the provided function, then decrements the indentation level and writes a closing }.

Source

pub fn restart_block<S>(&mut self, s: S)
where S: AsRef<str>,

Closes the current indented block and starts a new one at the same indentation level.

Specifically, the method writes the line } s { into the buffer at one less than the buffer’s indentation level.

§Panics

Panics if the current indentation level is zero.
