pub struct CodeBuffer { /* private fields */ }

Responsible for buffering code.

Implementations

impl CodeBuffer

Constants

pub const DEFAULT_INDENT: &'static str = " "

The default indent. (4 spaces)

pub const DEFAULT_LINE_ENDING: &'static str = "\n"

The default line-ending.

pub const DEFAULT_CAPACITY: usize = 4_096usize

The default buffer capacity.

impl CodeBuffer

Construction

pub fn new(indent: &str, line_ending: &str, capacity: usize) -> Self

Creates a new code buffer.

impl CodeBuffer

Writing

pub fn write(&mut self, code: &str)

Writes the code.

pub fn indent(&mut self, level: usize)

Writes the indent level.

pub fn end_line(&mut self)

Writes a line-ending.

pub fn line(&mut self, level: usize, code: &str)

Writes the code at the indent level with a line-ending.

pub fn space(&mut self)

Writes a single space.

impl CodeBuffer

Access

pub fn peek(&self) -> &str

Peeks at the buffered code.

pub fn export(self) -> String

Exports the buffered code.

pub fn clear(&mut self)

Clears the buffered code.

impl CodeBuffer

Display

pub fn display_statement<S>(statement: &S) -> String

where S: Statement,

Converts the statement to a string using the default code buffer.

pub fn display_expression<E>(expression: &E) -> String

where E: Expression,

Converts the expression to a string using the default code buffer.
