Enum SampleSize 

pub enum SampleSize {
    Records(usize),
    Bytes(usize),
    All,
}

Sample size configuration for sniffing.

Variants

Records(usize)

Sample a specific number of records.

Bytes(usize)

Sample a specific number of bytes.

All

Read the entire file.

Warning

This loads the entire file into memory. For large files (e.g., >100 MB), prefer SampleSize::Bytes with a reasonable limit to avoid excessive memory usage.

Implementations

impl SampleSize

pub fn records(&self) -> Option<usize>

Returns the number of records to sample, or None for All.

pub fn bytes(&self) -> Option<usize>

Returns the number of bytes to sample, or None for other modes.

Trait Implementations

impl Clone for SampleSize

fn clone(&self) -> SampleSize

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SampleSize

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

Formats the value using the given formatter.

impl Default for SampleSize

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for SampleSize

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Copy for SampleSize
