Function parse_policy_block 

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

Parses a policy YAML block from a Markdown fence into a PolicyDef.

The function deserializes content as YAML into a PolicyConfig, applies name precedence (the fence header_name is used when present; an explicit payload name conflicts with the header; an absent name in both locations is an error), converts each policy rule into the AST via parse_policy_rule, and returns a PolicyDef with the resolved name and rules.

Errors

Returns a ConfigError::YamlParse if YAML deserialization fails, ConfigError::NameConflict if both header and payload provide different names, ConfigError::MissingName if no name is supplied, or any ConfigError produced while parsing policy rules.

Examples

use cellstate_pipeline::parse_policy_block;

let yaml = r#"
name: example-policy
rules:
  - trigger: task_end
    actions:
      - type: summarize
        target: "summary-target"
"#;
let def = parse_policy_block(None, yaml).unwrap();
assert_eq!(def.name, "example-policy");
assert_eq!(def.rules.len(), 1);
