Struct bdk_chain::DescriptorId

source ·
pub struct DescriptorId(pub Hash);
Expand description

Represents the unique ID of a descriptor.

This is useful for having a fixed-length unique representation of a descriptor, in particular, we use it to persist application state changes related to the descriptor without having to re-write the whole descriptor each time.
