Implementations

impl IoCounters

pub fn chars_read(
    &self
) -> Quantity<dyn Dimension<N = Z0, J = Z0, L = Z0, I = Z0, Kind = dyn InformationKind + 'static, M = Z0, T = Z0, Th = Z0> + 'static, dyn Units<u64, luminous_intensity = candela, mass = kilogram, amount_of_substance = mole, length = meter, thermodynamic_temperature = kelvin, electric_current = ampere, time = second> + 'static, u64>

The number of bytes which this task has caused to be read from storage.

pub fn chars_written(
    &self
) -> Quantity<dyn Dimension<N = Z0, J = Z0, L = Z0, I = Z0, Kind = dyn InformationKind + 'static, M = Z0, T = Z0, Th = Z0> + 'static, dyn Units<u64, luminous_intensity = candela, mass = kilogram, amount_of_substance = mole, length = meter, thermodynamic_temperature = kelvin, electric_current = ampere, time = second> + 'static, u64>

The number of bytes which this task has caused, or shall cause to be written to disk.

pub fn read_syscalls(&self) -> u64

Attempt to count the number of read I/O operations, i.e. syscalls like read() and pread().

pub fn write_syscalls(&self) -> u64

Attempt to count the number of write I/O operations, i.e. syscalls like write() and pwrite().

pub fn bytes_read(
    &self
) -> Quantity<dyn Dimension<N = Z0, J = Z0, L = Z0, I = Z0, Kind = dyn InformationKind + 'static, M = Z0, T = Z0, Th = Z0> + 'static, dyn Units<u64, luminous_intensity = candela, mass = kilogram, amount_of_substance = mole, length = meter, thermodynamic_temperature = kelvin, electric_current = ampere, time = second> + 'static, u64>

Attempt to count the number of bytes which this process really did cause to be fetched from the storage layer.

pub fn bytes_written(
    &self
) -> Quantity<dyn Dimension<N = Z0, J = Z0, L = Z0, I = Z0, Kind = dyn InformationKind + 'static, M = Z0, T = Z0, Th = Z0> + 'static, dyn Units<u64, luminous_intensity = candela, mass = kilogram, amount_of_substance = mole, length = meter, thermodynamic_temperature = kelvin, electric_current = ampere, time = second> + 'static, u64>

Attempt to count the number of bytes which this process caused to be sent to the storage layer.

pub fn cancelled_write_bytes(
    &self
) -> Quantity<dyn Dimension<N = Z0, J = Z0, L = Z0, I = Z0, Kind = dyn InformationKind + 'static, M = Z0, T = Z0, Th = Z0> + 'static, dyn Units<u64, luminous_intensity = candela, mass = kilogram, amount_of_substance = mole, length = meter, thermodynamic_temperature = kelvin, electric_current = ampere, time = second> + 'static, u64>

The number of bytes which this process caused to not happen, by truncating pagecache.
