Struct sanakirja::CowPage[−][src]

#[repr(C)]pub struct CowPage {
    pub data: *mut u8,
    pub offset: u64,
}

Representation of a mutable or shared page. This is an owned page (like Vec in Rust’s std), but we do not know whether we can mutate it or not.

The least-significant bit of the first byte of each page is 1 if and only if the page was allocated by the current transaction (and hence isn’t visible to any other transaction, meaning we can write on it).

Fields

data: *mut u8offset: u64
