Struct MemSizeArgs

pub struct MemSizeArgs {
    pub l1: usize,
    pub disk: usize,
    pub fill_factor: f32,
}

Fields

l1: usize

Size of the L1 cache memory, in kilobytes (kB). It correspond to the page size of a DBMS.

disk: usize

Size of the HDD cache size, in kilobytes (kB)

fill_factor: f32

Fill factor: to prevent occupying the full l1 cache memory

Implementations

impl MemSizeArgs

pub fn l1_byte_size(&self) -> usize

Returns the size of the l1 cache, in bytes.

pub fn disk_byte_size(&self) -> usize

Returns the size of the disk cache, in bytes.

Trait Implementations

impl Debug for MemSizeArgs

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

Formats the value using the given formatter.

impl StructOpt for MemSizeArgs

fn clap<'a, 'b>() -> App<'a, 'b>

Returns clap::App corresponding to the struct.

fn from_clap(matches: &ArgMatches<'_>) -> Self

Builds the struct from clap::ArgMatches. It’s guaranteed to succeed if matches originates from an App generated by StructOpt::clap called on the same type, otherwise it must panic.

fn from_args() -> Self

where Self: Sized,

Builds the struct from the command line arguments (std::env::args_os). Calls clap::Error::exit on failure, printing the error message and aborting the program.

fn from_args_safe() -> Result<Self, Error>

where Self: Sized,

Builds the struct from the command line arguments (std::env::args_os). Unlike StructOpt::from_args, returns clap::Error on failure instead of aborting the program, so calling .exit is up to you.

fn from_iter<I>(iter: I) -> Self

where Self: Sized, I: IntoIterator, <I as IntoIterator>::Item: Into<OsString> + Clone,

Gets the struct from any iterator such as a Vec of your making. Print the error message and quit the program in case of failure.

fn from_iter_safe<I>(iter: I) -> Result<Self, Error>

where Self: Sized, I: IntoIterator, <I as IntoIterator>::Item: Into<OsString> + Clone,

Gets the struct from any iterator such as a Vec of your making.
