Struct Builder 

pub struct Builder {
    pub is_executable: bool,
    /* private fields */
}

Main entry for the build script

Fields

is_executable: bool

if true, an executable called this function

Implementations

impl Builder

pub fn new() -> Self

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

override the settings

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

override the settings

pub fn file(&mut self, filename: &str) -> &mut Self

set input file

pub fn note_conflicts(&mut self, val: bool) -> &mut Self

Print note information about any shift/reduce, reduce/reduce conflicts. If the target is deterministic parser, conflict will be treated as an error, so this option will be ignored. This option is only for non-deterministic GLR parser.

pub fn note_conflicts_resolving(&mut self, val: bool) -> &mut Self

Print debug information about conflicts resolving process by any %left, %right, or %precedence directive.

pub fn note_optimization(&mut self, val: bool) -> &mut Self

Print debug information about optimization process.

pub fn note_on_stderr(&mut self, val: bool) -> &mut Self

Print every note_* information to stderr.

pub fn note_backtrace(&mut self, val: bool) -> &mut Self

Print backtrace of production rules when conflicts occurred. ruleset could be messed up

pub fn build(&self, output_file: &str)

build and emit code to output file

pub fn build_impl(&self) -> Result<Output, String>

for internal use

Trait Implementations

impl Default for Builder

fn default() -> Self

Returns the “default value” for a type.
