# Trait EarlyCheckNode

Source

    pub trait EarlyCheckNode<'a>: Copy {
        // Required methods
        fn id(self) -> NodeId;
        fn attrs(self) -> &'a [Attribute];

Expand description

Early lints work on different nodes - either on the crate root, or on freshly loaded modules. This trait generalizes over those nodes.

## Required Methods§

Source

#### fn id(self) -> NodeId

Source

#### fn attrs(self) -> &'a [Attribute]

Source

#### fn check<'ecx, 'tcx, T: EarlyLintPass>( self, cx: &mut EarlyContextAndPass<'ecx, 'tcx, T>, )

## Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
