Fields

input: PathBuf

Input CSV file to process

output: Option<PathBuf>

Output CSV file (stdout if omitted)

schema: Option<PathBuf>

Schema file to drive typed operations and apply value replacements

index: Option<PathBuf>

Existing index file to speed up operations

index_variant: Option<String>

Specific index variant name to use from the selected index file

sort: Vec<String>

Sort directives of the form column[:asc|desc]

columns: Vec<String>

Restrict output to this comma-separated list of columns

exclude_columns: Vec<String>

Exclude this comma-separated list of columns from output

derives: Vec<String>

Additional derived columns using name=expression

filters: Vec<String>

Row-level filters such as amount>=100 or status = shipped

filter_exprs: Vec<String>

Evalexpr-based filter expressions that must evaluate to truthy values

row_numbers: bool

Emit 1-based row numbers as the first column

limit: Option<usize>

Limit number of rows emitted

delimiter: Option<u8>

CSV delimiter character for reading input

output_delimiter: Option<u8>

Delimiter to use for output (defaults to input delimiter)

input_encoding: Option<String>

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

output_encoding: Option<String>

Character encoding for the output file/stdout (defaults to utf-8)

boolean_format: BooleanFormat

Normalize boolean columns in output

preview: bool

Render results as a preview table on stdout (disables –output and defaults the row limit)

table: bool

Render output as an elastic table to stdout

apply_mappings: bool

Apply schema-defined datatype mappings before replacements (auto when available)

skip_mappings: bool

Skip schema-defined datatype mappings even if they exist

Trait Implementations

impl Args for ProcessArgs

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 ProcessArgs

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

Formats the value using the given formatter.

impl FromArgMatches for ProcessArgs

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.
