Struct CompileEnvironment

pub struct CompileEnvironment {
    use_line: bool,
    line: u32,
    specials: Option<Specials>,
    global_map: HashMap<Interned, usize>,
    gensym_idx: usize,
    namespace: Namespace,
    noop_map: HashMap<String, Value>,
}

Fields

use_line: bool

line: u32

specials: Option<Specials>

global_map: HashMap<Interned, usize>

gensym_idx: usize

namespace: Namespace

noop_map: HashMap<String, Value>

Some functions can be swapped to/from a noop at runtime for various reasons, e.g. make sure nothing can write to stdout; this field tracks the Value the function should point to so the user can swap that back in when they no longer want it to be a noop.

Implementations

impl CompileEnvironment

pub fn new() -> Self

pub fn next_gensym(&mut self) -> usize

pub fn line(&self) -> u32

pub fn set_namespace(&mut self, namespace: Namespace)

pub fn add_ns_import(&mut self, ns: String, alias: Option<String>)

pub fn get_namespace(&self) -> &Namespace

pub fn save_noop(&mut self, s: String, v: Value) -> Option<Value>

Set a given function’s original Value function so that it can be replaced with noop fn but mapped back later.

pub fn remove_noop(&mut self, t: impl AsRef<str>) -> Option<Value>

Removes a key from the map, returning the value at the key if the key was previously in the map. This is that original function’s Value.

Trait Implementations

impl Default for CompileEnvironment

fn default() -> Self

Returns the “default value” for a type.
