Trait conserve::ReadTree

pub trait ReadTree: HasReport {
    type E: Entry;
    type I: Iterator<Item = Result<Self::E>>;
    type R: Read;

    fn iter_entries(&self, report: &Report) -> Result<Self::I>;
    fn file_contents(&self, entry: &Self::E) -> Result<Self::R>;
    fn estimate_count(&self) -> Result<u64>;

    fn size(&self) -> Result<TreeSize> { ... }
}

Abstract Tree that may be either on the real filesystem or stored in an archive.

Required Associated Types

type E: Entry

type I: Iterator<Item = Result<Self::E>>

type R: Read

Required Methods

fn iter_entries(&self, report: &Report) -> Result<Self::I>

fn file_contents(&self, entry: &Self::E) -> Result<Self::R>

fn estimate_count(&self) -> Result<u64>

Estimate the number of entries in the tree. This might do somewhat expensive IO, so isn’t the Iter’s size_hint.

Provided Methods

fn size(&self) -> Result<TreeSize>

Measure the tree size: typically requires walking all entries so takes a while.
