Fields

full_hash: u64

Hash of the full HTML content

content_hash: u64

Hash of just the main content (excluding nav, footer, etc.)

text_hash: u64

Hash of the text content only (no tags)

structure_hash: u64

Hash of the document structure (tag hierarchy)

element_count: usize

Number of elements in the document

text_node_count: usize

Number of text nodes

content_length: usize

Content length in bytes

main_content_length: usize

Main content length

Implementations

impl ContentFingerprint

pub fn has_changed(&self, other: &ContentFingerprint) -> bool

Check if content has changed compared to another fingerprint

pub fn has_minor_changes(&self, other: &ContentFingerprint) -> bool

Check if only minor changes occurred (same structure, different content)

pub fn has_structural_changes(&self, other: &ContentFingerprint) -> bool

Check if structure changed (major change)

pub fn similarity(&self, other: &ContentFingerprint) -> f64

Get similarity percentage (0.0 to 1.0)

Trait Implementations

impl Clone for ContentFingerprint

fn clone(&self) -> ContentFingerprint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContentFingerprint

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

Formats the value using the given formatter.

impl Default for ContentFingerprint

fn default() -> ContentFingerprint

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ContentFingerprint

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ContentFingerprint

fn eq(&self, other: &ContentFingerprint) -> 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 Serialize for ContentFingerprint

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ContentFingerprint
