Struct ClojureEdnCodecLib 

pub struct ClojureEdnCodecLib { /* private fields */ }

Loadable Lib that registers the ClojureEdnCodec as a runtime codec object.

Exports a single Export::Codec under clojure_edn_reader_symbol and installs it via the Linker when loaded.

Examples

Load the codec and decode a small EDN form into the shared Expr graph:

use std::sync::Arc;
use sim_codec::{Input, decode_tree_with_codec};
use sim_kernel::{
    CapabilitySet, Cx, DefaultFactory, Expr, NoopEvalPolicy, ReadPolicy, TrustLevel,
};
use sim_lib_lang_clojure::{ClojureEdnCodecLib, clojure_edn_reader_symbol};

let mut cx = Cx::new(Arc::new(NoopEvalPolicy), Arc::new(DefaultFactory));
let codec_id = cx.registry_mut().fresh_codec_id();
cx.load_lib(&ClojureEdnCodecLib::new(codec_id))?;

let policy = ReadPolicy {
    trust: TrustLevel::TrustedSource,
    capabilities: CapabilitySet::new(),
};
let tree = decode_tree_with_codec(
    &mut cx,
    &clojure_edn_reader_symbol(),
    Input::Text("[1 2 3]".to_owned()),
    policy,
    "doc.edn",
)?;
assert!(matches!(tree.expr, Expr::Vector(_)));

Implementations

impl ClojureEdnCodecLib

pub fn new(id: CodecId) -> Self

Builds the codec lib bound to the given runtime CodecId.

Trait Implementations

impl Lib for ClojureEdnCodecLib

fn manifest(&self) -> LibManifest

Returns the library’s manifest.

fn load(&self, _cx: &mut LoadCx, linker: &mut Linker<'_>) -> Result<()>

Registers the library’s exports against the registry via linker.

fn unload(&self, _cx: &mut Cx, _linker: &mut Linker<'_>) -> Result<(), Error>

Tears down external resources that cannot be represented in the registry’s recorded load delta.
