Struct FormatReadPlan 

Source 
pub struct FormatReadPlan<'a, S: Storage + 'static> { /* private fields */ }
Expand description

Resolved read plan for a disk image range.

A read plan describes how a requested image range maps to storage ranges, zero-filled ranges, end-of-file ranges, or special format-driver ranges. It does not issue I/O and does not allocate or modify image metadata.

Implementations§
