Struct MkAlgoArgs

pub struct MkAlgoArgs {
    pub chunk_size: usize,
    pub kway: usize,
    pub temp: PathBuf,
    /* private fields */
}

Fields

chunk_size: usize

Number of rows process at the same time: must be as large as possible but must fit in memory.

Also equals the number of rows in a temporary file.

kway: usize

‘k’ value of the external k-way merge sort, i.e. maximum number of temporary files merge at the same time.

temp: PathBuf

Temporary directory containing temporary files

Implementations

impl MkAlgoArgs

pub fn get_tmp_dir(&self) -> Result<TmpDir, Error>

pub fn get_output(&self) -> PathBuf

Trait Implementations

impl Debug for MkAlgoArgs

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

Formats the value using the given formatter.

impl StructOpt for MkAlgoArgs

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.
