Struct Validator 

pub struct Validator { /* private fields */ }

A compiled schema, or the reason there is none.

Implementations

impl Validator

pub fn compile(what: &str, schema_text: &str) -> Option<Self>

Compile a schema, or decide there is nothing to check against.

Ok(None) — deliberately not an error — when the text is not a usable schema. The alternative is refusing every call to a component whose packaging is wrong, which converts a build-time mistake into a total outage for something whose arguments may be perfectly fine. The component’s own SDK validates too; this layer is the second of two, and the one that can afford to be absent.

The reason is logged at warn with the tool named, once per compile, because a component silently running unvalidated is exactly the state an operator would want to know about.

pub fn check(&self, value: &Value) -> Result<(), String>

Check one value. Err carries the message the agent sees.
