Struct taschenrechner::prelude::Env[−][src]

pub struct Env(_);

Contains all variables and functions as definitions. Use Default to initiate with common definitions.

Implementations

impl Env[src]

pub fn new() -> Env[src]

Default is recommended instead, because it contains common definitions.

pub fn get(&self, symbol: &Symbol) -> Result<&Def, TypeErr>[src]

Return a definition by symbol.

pub fn insert(&mut self, symbol: Symbol, def: Def) -> Option<Def>[src]

Define new definition.

pub fn remove(&mut self, symbol: Symbol) -> Option<Def>[src]

Remove definition by symbol.

pub fn load(path: &str) -> Result<Env, String>[src]

Loads a file of definitions. The crate come with default_env.txt. Did work with WASM, probably because it is an internal file.
