Trait ExternalResolve 

pub trait ExternalResolve {
    type Resolved<'a>;

    // Required method
    fn resolve<'a>(
        view: &'a AccountView<'a>,
    ) -> Result<Self::Resolved<'a>, ProgramError>;
}

Owner/discriminator-selected resolver for external account families.

Use this for account sets such as Pyth/Switchboard/custom oracle unions or Token/Token-2022 interfaces where the account owner decides which zero-copy view should be used at runtime.

Required Associated Types

type Resolved<'a>

Guard-owned resolved view.

Required Methods

fn resolve<'a>( view: &'a AccountView<'a>, ) -> Result<Self::Resolved<'a>, ProgramError>

Resolve the account into one of the supported external views.

This trait is not dyn compatible.

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