Struct fasteval::parser::Parser

pub struct Parser {
    pub expr_len_limit: usize,
    pub expr_depth_limit: usize,
}

Fields

expr_len_limit: usize

expr_depth_limit: usize

Methods

impl Parser

pub const fn new() -> Self

pub fn parse(
    &self,
    expr_str: &str,
    slab: &mut ParseSlab
) -> Result<ExpressionI, Error>

Use this function to parse an expression String. The Slab will be cleared first.

pub fn parse_noclear(
    &self,
    expr_str: &str,
    slab: &mut ParseSlab
) -> Result<ExpressionI, Error>

This is exactly the same as parse() but the Slab will NOT be cleared. This is useful in performance-critical sections, when you know that you already have an empty Slab.

This function cannot return Result<&Expression> because it would prolong the mut ref. / That's why we return an ExpressionI instead.

impl Default for Parser

fn default() -> Self

Returns the "default value" for a type.
