Struct glommio::RingIoStats

pub struct RingIoStats { /* fields omitted */ }

Stores information about IO performed in a specific ring

Implementations

impl RingIoStats

pub fn files_opened(&self) -> u64

The total amount of files opened in this executor so far.

files_opened - files_closed gives the current open files count

pub fn files_closed(&self) -> u64

The total amount of files closed in this executor so far.

files_opened - files_closed gives the current open files count

pub fn file_reads(&self) -> (u64, u64)

File read IO stats

Returns the number of individual read ops as well as bytes read

pub fn file_deduped_reads(&self) -> (u64, u64)

File read IO stats (deduplicated)

Returns the number of reads that fed from another preexisting buffer

pub fn file_buffered_reads(&self) -> (u64, u64)

Buffered file read IO stats

Returns the number of individual buffered read ops as well as bytes read

pub fn file_writes(&self) -> (u64, u64)

File write IO stats

Returns the number of individual write ops as well as bytes written

pub fn file_buffered_writes(&self) -> (u64, u64)

Buffered file write IO stats

Returns the number of individual buffered write ops as well as bytes written
