Trait PayloadAttributesBuilder 

pub trait PayloadAttributesBuilder<Attributes, Header = Header>:
    Send
    + Sync
    + 'static {
    // Required method
    fn build(&self, parent: &SealedHeader<Header>) -> Attributes;
}

Factory trait for creating payload attributes.

Enables different strategies for generating payload attributes based on contextual information. Useful for testing and specialized building.

Required Methods

fn build(&self, parent: &SealedHeader<Header>) -> Attributes

Constructs new payload attributes for the given timestamp.

Trait Implementations

impl<Attributes, Header> PayloadAttributesBuilder<Attributes, Header> for Box<dyn PayloadAttributesBuilder<Attributes, Header>>

where Header: 'static, Attributes: 'static,

fn build(&self, parent: &SealedHeader<Header>) -> Attributes

Constructs new payload attributes for the given timestamp.

Dyn Compatibility

This trait is dyn compatible.

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