Implementations

impl PrintFormat

pub fn print_batches( &self, batches: &[RecordBatch], maxrows: MaxRows ) -> Result<()>

print the batches to stdout using the specified format maxrows option is only used for Table format: If maxrows is Some(n), then at most n rows will be displayed If maxrows is None, then every row will be displayed

Trait Implementations

impl Clone for PrintFormat

fn clone(&self) -> PrintFormat

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PrintFormat

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

Formats the value using the given formatter.

impl FromStr for PrintFormat

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for PrintFormat

fn eq(&self, other: &PrintFormat) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ValueEnum for PrintFormat

fn value_variants<'a>() -> &'a [Self]

All possible argument values, in display order.

fn to_possible_value<'a>(&self) -> Option<PossibleValue<'a>>

The canonical argument value.

fn from_str(input: &str, ignore_case: bool) -> Result<Self, String>

Parse an argument into Self.
