Struct ArgumentValidators 

pub struct ArgumentValidators { /* private fields */ }

A tool-name to ArgumentValidator registry.

Registration is LAST-ONE-WINS, and a replacement is announced once by a tracing::warn! — a silently discarded validator is a rule the operator believes is enforced and is not.

Implementations

impl ArgumentValidators

pub fn new() -> Self

An empty registry.

pub fn insert( &mut self, tool: impl Into<String>, validator: Arc<dyn ArgumentValidator>, )

Register validator for the tool named tool, REPLACING any validator already registered under that name and warning once when it does.

pub fn get(&self, tool: &str) -> Option<Arc<dyn ArgumentValidator>>

The validator registered for tool, if any.

pub fn is_empty(&self) -> bool

Whether any validator is registered.

pub fn len(&self) -> usize

How many validators are registered.

pub fn names(&self) -> Vec<&str>

Registered tool names, sorted, so the startup log is deterministic.
