Trait PackageLinkVisitor 

pub trait PackageLinkVisitor<'g> {
    // Required method
    fn visit_link(
        &mut self,
        cx: &PackageLinkContext<'g>,
        link: PackageLink<'g>,
    ) -> bool;
}

Represents whether a particular link within a package graph should be followed during a resolve operation.

Required Methods

fn visit_link( &mut self, cx: &PackageLinkContext<'g>, link: PackageLink<'g>, ) -> bool

Returns true if this link should be followed during a resolve operation.

Returning false does not prevent the to package (or from package with query_reverse) from being included if it’s reachable through other means.

Trait Implementations

impl<'g> PackageLinkVisitor<'g> for Box<dyn PackageLinkVisitor<'g> + '_>

fn visit_link( &mut self, cx: &PackageLinkContext<'g>, link: PackageLink<'g>, ) -> bool

Returns true if this link should be followed during a resolve operation.

impl<'g> PackageLinkVisitor<'g> for &mut dyn PackageLinkVisitor<'g>

fn visit_link( &mut self, cx: &PackageLinkContext<'g>, link: PackageLink<'g>, ) -> bool

Returns true if this link should be followed during a resolve operation.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
