Trait BlockSource

pub trait BlockSource {
    type Error;

    // Required method
    fn with_blocks<F, WalletErrT>(
        &self,
        from_height: Option<BlockHeight>,
        limit: Option<usize>,
        with_block: F,
    ) -> Result<(), Error<WalletErrT, Self::Error>>
       where F: FnMut(CompactBlock) -> Result<(), Error<WalletErrT, Self::Error>>;
}

This trait provides sequential access to raw blockchain data via a callback-oriented API.

Required Associated Types

type Error

Required Methods

fn with_blocks<F, WalletErrT>( &self, from_height: Option<BlockHeight>, limit: Option<usize>, with_block: F, ) -> Result<(), Error<WalletErrT, Self::Error>>

where F: FnMut(CompactBlock) -> Result<(), Error<WalletErrT, Self::Error>>,

Scan the specified limit number of blocks from the blockchain, starting at from_height, applying the provided callback to each block. If from_height is None then scanning will begin at the first available block.

• WalletErrT: the types of errors produced by the wallet operations performed as part of processing each row.
• NoteRefT: the type of note identifiers in the wallet data store, for use in reporting errors related to specific notes.

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.
