Fields

input: PathBuf

Input CSV file to index

index: PathBuf

Output index file (.idx)

columns: Vec<String>

Columns to include in a single ascending index (deprecated when –spec is used)

specs: Vec<String>

Repeatable index specifications such as col_a:asc,col_b:desc or fast=col_a:asc

coverings: Vec<String>

Generate covering index variants by expanding column prefixes and direction combinations (use | to separate directions)

schema: Option<PathBuf>

Optional schema file describing column types

limit: Option<usize>

Limit number of rows to scan (useful for prototyping)

delimiter: Option<u8>

CSV delimiter character (supports ‘,’, ‘tab’, ‘;’, ‘|’)

input_encoding: Option<String>

Character encoding of the input file (defaults to utf-8)

Trait Implementations

impl Args for IndexArgs

fn group_id() -> Option<Id>

Report the ArgGroup::id for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate Self via FromArgMatches::from_arg_matches_mut

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate self via FromArgMatches::update_from_arg_matches_mut

impl Debug for IndexArgs

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

Formats the value using the given formatter.

impl FromArgMatches for IndexArgs

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

fn update_from_arg_matches_mut( &mut self, __clap_arg_matches: &mut ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.
