Struct OpDef 

pub struct OpDef {
    pub src: Vec<String>,
    pub osrc: String,
    pub csrc: String,
    pub left: Option<i64>,
    pub right: Option<i64>,
    pub prefix: bool,
    pub suffix: bool,
    pub infix: bool,
    pub ternary: bool,
    pub paren: bool,
    pub preval: Option<PrevalDef>,
    pub use_data: Value,
}

One entry of the op option map: the definition of an operator.

src carries one source string for a prefix, suffix or infix operator and two for a ternary (["?", ":"]); a paren operator uses osrc and csrc instead.

Fields

src: Vec<String>

osrc: String

csrc: String

left: Option<i64>

right: Option<i64>

prefix: bool

suffix: bool

infix: bool

ternary: bool

paren: bool

preval: Option<PrevalDef>

use_data: Value

Custom operator data, handed back to an evaluator as op.use.

Implementations

impl OpDef

pub fn infix(src: impl Into<String>, left: i64, right: i64) -> Self

An infix operator with the given source and binding powers.

pub fn prefix(src: impl Into<String>, right: i64) -> Self

A prefix operator with the given source and right binding power.

pub fn suffix(src: impl Into<String>, left: i64) -> Self

A suffix operator with the given source and left binding power.

pub fn ternary(first: impl Into<String>, second: impl Into<String>) -> Self

A ternary operator with its two source strings.

pub fn paren(osrc: impl Into<String>, csrc: impl Into<String>) -> Self

A paren operator with its opening and closing source strings.

pub fn with_preval(self, preval: PrevalDef) -> Self

Give a paren operator a preval configuration.

pub fn with_use(self, use_data: Value) -> Self

Attach custom operator data, handed back to an evaluator.
