std::boolean

std::boolean provides a no-allocation boxed wrapper around the built-in bool primitive for method-oriented APIs.

Exported API#

module std::boolean;

export enum ParseErrorKind {
  InvalidInput,
}

export error ParseFailed {
  code: int,
}

export struct Boolean {
  value: bool,
}

impl Boolean {
  public fn from_bool (value: bool) -> Boolean;
  public fn parse (value: string) -> std::result::Result(Boolean, ParseFailed);
  public fn as_bool (self: &Boolean) -> bool;
  public fn is_true (self: &Boolean) -> bool;
  public fn is_false (self: &Boolean) -> bool;
  public fn not (self: &Boolean) -> Boolean;
}

Notes#

• Boolean is an inline wrapper. It does not allocate.
• Parsing accepts only the exact lower-case spellings "true" and "false".
