Function parse_adapter_block 

pub fn parse_adapter_block(
    header_name: Option<&str>,
    content: &str,
) -> Result<AdapterDef, ConfigError>

Parses an adapter YAML fence block into an AdapterDef.

The function deserializes content as YAML, determines the adapter name using the fence header if present (erroring on conflicts or absence), validates the adapter configuration, and converts it into an AdapterDef.

Errors

Returns a ConfigError when:

• YAML deserialization fails (ConfigError::YamlParse),
• both a header name and a payload name are provided (ConfigError::NameConflict),
• no name is provided (ConfigError::MissingName),
• the adapter type is unrecognized (ConfigError::UnknownAdapter),
• or other validation failures occur.

Examples

use cellstate_pipeline::parse_adapter_block;

let header = Some("my_adapter");
let yaml = r#"
adapter_type: "postgres"
connection: "postgres://user:pass@localhost/db"
options: []
"#;
let def = parse_adapter_block(header, yaml).expect("should parse");
assert_eq!(def.name, "my_adapter");
