Struct Hierarchy 

pub struct Hierarchy {
    pub is_a: Csr,
    pub closure: Closure,
}

The is-a adjacency and its closure, as one artifact.

Fields

is_a: Csr

Child-to-parent adjacency.

closure: Closure

The transitive closure of is_a.

Implementations

impl Hierarchy

pub fn size_in_bytes(&self) -> usize

The heap bytes the adjacency and the closure hold (crate::footprint).

pub fn write_to(&self, out: &mut impl Write) -> Result<(), PersistError>

Writes the layout.

Errors

Returns PersistError::Io when writing fails.

pub fn read_from(input: &mut impl Read) -> Result<Self, PersistError>

Reads the layout.

Errors

Returns PersistError for a truncated, foreign, or inconsistent artifact.
