Struct RawCtxBindingBuilder 

pub struct RawCtxBindingBuilder { /* private fields */ }

Builder that emits invocation-descriptor metadata for RawCtx inputs.

Implementations

impl RawCtxBindingBuilder

pub fn new() -> Self

Create an empty binding builder.

pub fn keyword(arg: impl Into<String>) -> Self

Convenience constructor for keyword arguments.

pub fn positional() -> Self

Convenience constructor for positional arguments.

pub fn arg(self, arg: impl Into<String>) -> Self

Assign the argument name that should receive the decoded value.

pub fn mode(self, mode: impl Into<String>) -> Self

Override the binding mode (keyword or positional).

pub fn decoder(self, decoder: impl Into<String>) -> Self

Configure the decoder to use (utf8, json, bytes, memoryview, float64, etc.).

pub fn option(self, key: impl Into<String>, value: JsonValue) -> Self

Attach decoder-specific options (stored under options).

pub fn metadata_arg(self, name: impl Into<String>) -> Self

Name the keyword argument that should receive metadata for the buffer.

pub fn raw_arg(self, name: impl Into<String>) -> Self

Name the keyword argument that should receive the raw payload record.

pub fn python_loader(self, expression: impl Into<String>) -> Self

Provide a Python loader expression evaluated with buffer, metadata, and payload.

pub fn default_value(self, value: JsonValue) -> Self

Fallback value used when the payload is missing or the decoder returns None.

pub fn optional(self, optional: bool) -> Self

Mark the binding optional (missing payload becomes None instead of error).

pub fn enabled(self, enabled: bool) -> Self

Enable or disable the binding.

pub fn table(self, table: RawCtxTableSpec) -> Self

Attach a table schema describing a dict-of-columns structure that the shim should build.

pub fn build(self) -> JsonValue

Serialise the builder into descriptor metadata (serde_json::Value).

pub fn merge_into(self, metadata: &mut JsonValue)

Merge the binding into an existing metadata object (mutating it in place).
