Struct BlockProfile 

pub struct BlockProfile {
    pub cid: String,
    pub raw_size_bytes: u64,
    pub compressed_size_bytes: Option<u64>,
    pub codec: Option<CompressionCodec>,
    pub access_count: u64,
}

Profile tracking the size and access characteristics of a single block.

Fields

cid: String

Content identifier of the block.

raw_size_bytes: u64

Size of the block before any compression is applied, in bytes.

compressed_size_bytes: Option<u64>

Size after compression, if the block has been compressed.

codec: Option<CompressionCodec>

Codec used for the current compressed copy, if any.

access_count: u64

Number of times this block has been accessed.

Implementations

impl BlockProfile

pub fn compression_ratio(&self) -> f64

Returns the achieved compression ratio (raw / compressed).

Returns 1.0 when compression data is unavailable.

pub fn space_savings_bytes(&self) -> u64

Returns the number of bytes saved by compression (raw − compressed).

Returns 0 when the block has not been compressed or when compression actually expanded the block (saturating subtraction).

Trait Implementations

impl Clone for BlockProfile

fn clone(&self) -> BlockProfile

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BlockProfile

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for BlockProfile

fn eq(&self, other: &BlockProfile) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
