Enum UnicodeNorm 

pub enum UnicodeNorm {
    None,
    Nfc,
    Nfd,
    Nfkc,
    Nfkd,
}

Unicode normalization form to apply to extracted text.

Different PDF generators may produce different Unicode representations for the same visual text (e.g., composed vs. decomposed accented chars). Normalizing ensures consistent text output regardless of the source.

Variants

None

No normalization (default).

Nfc

Canonical Decomposition, followed by Canonical Composition (NFC).

Nfd

Canonical Decomposition (NFD).

Nfkc

Compatibility Decomposition, followed by Canonical Composition (NFKC).

Nfkd

Compatibility Decomposition (NFKD).

Implementations

impl UnicodeNorm

pub fn normalize(&self, text: &str) -> String

Apply this normalization form to the given string.

Returns the input unchanged if normalization is None.

Trait Implementations

impl Clone for UnicodeNorm

fn clone(&self) -> UnicodeNorm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UnicodeNorm

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

Formats the value using the given formatter.

impl Default for UnicodeNorm

fn default() -> UnicodeNorm

Returns the “default value” for a type.

impl PartialEq for UnicodeNorm

fn eq(&self, other: &UnicodeNorm) -> 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 UnicodeNorm

impl Eq for UnicodeNorm

impl StructuralPartialEq for UnicodeNorm
