Struct ExternalCodec 

pub struct ExternalCodec { /* private fields */ }

A codec driven through the file-based CLI contract.

Construct directly (for tests) via ExternalCodec::new then the builder setters, or from a manifest via crate::manifest::CodecManifest::into_adapter.

Implementations

impl ExternalCodec

pub fn new(name: impl Into<String>, cmd: impl Into<PathBuf>) -> Self

A new codec with the default templates and formats.

pub fn with_prefix_args(self, args: Vec<String>) -> Self

Set the fixed prefix args (before the subcommand).

pub fn with_templates(self, encode: Vec<String>, decode: Vec<String>) -> Self

Override the encode / decode argument templates.

pub fn with_env(self, env: Vec<(String, String)>) -> Self

Set extra environment variables (merged over the ECS_* set).

pub fn with_declared_lossless(self, v: bool) -> Self

Set the lossless claim.

pub fn with_sample_dtype(self, d: SampleDtype) -> Self

Set the raw decode-stream integer width.

pub fn with_formats(self, input: InputFormat, output: OutputFormat) -> Self

Set the encode-input and decode-output file formats.

pub fn with_timeout(self, timeout: Duration) -> Self

Set the per-invocation timeout.

pub fn cmd(&self) -> &PathBuf
