Struct Stats

pub struct Stats {
    pub null: usize,
    pub lone_cr: usize,
    pub lone_lf: usize,
    pub crlf: usize,
    pub printable: usize,
    pub non_printable: usize,
}

Statistics about a buffer that helps to safely perform EOL conversions

Fields

null: usize

The amount of null bytes.

lone_cr: usize

The amount of lone carriage returns (\r).

lone_lf: usize

The amount of lone line feeds (\n).

crlf: usize

The amount carriage returns followed by line feeds

printable: usize

The estimate of printable characters.

non_printable: usize

The estimate of characters that can’t be printed.

Implementations

impl Stats

pub fn from_bytes(bytes: &[u8]) -> Self

Gather statistics from the given bytes.

Note that the entire buffer will be scanned.

pub fn is_binary(&self) -> bool

Returns true if these statistics are typical for a binary file.

pub fn will_convert_lf_to_crlf( &self, digest: AttributesDigest, config: Configuration, ) -> bool

Return true if we would convert the buffer from which these stats are derived, knowing only the digest

Trait Implementations

impl Clone for Stats

fn clone(&self) -> Stats

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Stats

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

Formats the value using the given formatter.

impl Default for Stats

fn default() -> Stats

Returns the “default value” for a type.

impl Hash for Stats

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Stats

fn cmp(&self, other: &Stats) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Stats

fn eq(&self, other: &Stats) -> 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 PartialOrd for Stats

fn partial_cmp(&self, other: &Stats) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
