Struct PersistentCachePieceContent 

pub struct PersistentCachePieceContent { /* private fields */ }

PersistentCachePieceContent represents a persistent cache piece metadata and piece content request.

Value Format:

• Metadata Length (4 bytes): Length of the metadata section.
• Number (4 bytes): Piece number to download.
• Offset (8 bytes): Byte offset in the file.
• Length (8 bytes): Length of the piece in bytes.
• Digest Length (4 bytes): Length of the digest field.
• Digest (variable): CRC32 hash of the piece content.
• Parent ID Length (4 bytes): Length of the parent task identifier.
• Parent ID (variable): Parent task identifier.
• Traffic Type (1 byte): Network traffic classification type.
• Cost (8 bytes): Download cost in seconds.
• Created At (8 bytes): Creation timestamp as Unix epoch seconds.
• Content (variable): Piece content bytes.

Implementations

impl PersistentCachePieceContent

PersistentCachePieceContent implements the PersistentCachePieceContent functions.

pub fn new( number: u32, offset: u64, length: u64, digest: String, parent_id: String, traffic_type: u8, cost: Duration, created_at: NaiveDateTime, ) -> Self

new creates a new PersistentCachePieceContent request.

pub fn metadata(&self) -> PersistentCachePieceMetadata

metadata returns the persistent cache piece metadata.

pub fn metadata_len(&self) -> u32

metadata_len returns the length of the metadata section.

pub fn is_empty(&self) -> bool

is_empty returns whether the persistent cache piece content request is empty.
