Trait CursorSecureExtract 

pub trait CursorSecureExtract {
    // Required methods
    fn extract_whitelisted_fields(
        &self,
        fields: &[String],
    ) -> Result<Vec<CursorValue>, CursorError>;
    fn encode(_cursor: &Cursor) -> Result<String, CursorError>;
    fn decode(_encoded: &str) -> Result<Vec<FilterValue>, CursorError>;
}

Security-First Cursor Field Whitelist Trait

This trait enforces a whitelist-based security model for cursor pagination fields. Implementors MUST explicitly whitelist each allowed field to prevent field injection attacks.

Required Methods

fn extract_whitelisted_fields( &self, fields: &[String], ) -> Result<Vec<CursorValue>, CursorError>

fn encode(_cursor: &Cursor) -> Result<String, CursorError>

Encode cursor to string token (JSON feature disabled)

fn decode(_encoded: &str) -> Result<Vec<FilterValue>, CursorError>

Decode string token to FilterValue vector (JSON feature disabled)

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.
