Struct Extractor 

pub struct Extractor { /* private fields */ }

An Extract implementation that does no validation (length checks, validity, etc).

Implementations

impl Extractor

pub fn new() -> Extractor

Create a new extractor that extracts URLs without a protocol.

pub fn extract_urls(&self, s: &str) -> Vec<String>

Extract a vector of URLs as String objects.

Trait Implementations

impl<'a> Extract<'a> for Extractor

type T = Vec<Entity<'a>>

Extractor returns a vector of entities with no validation data.

type Mention = Option<Entity<'a>>

Extractor returns a single mention entity with no validation data.

fn get_extract_url_without_protocol(&self) -> bool

Get whether the extractor will detect URLs without schemes, such as “example.com”.

fn set_extract_url_without_protocol( &mut self, extract_url_without_protocol: bool, )

Set whether the extractor will detect URLs without schemes, such as “example.com”.

fn extract(&self, s: &'a str, r_match: fn(Rule) -> bool) -> Vec<Entity<'a>>

Extract entities from the source text that match rules allowed by r_match.

fn create_result( &self, s: &'a str, count: usize, scanned: &mut Vec<UnprocessedEntity<'a>>, ) -> Vec<Entity<'a>>

Create the result type. The concrete type varies by implementation.

fn extract_reply_username(&self, s: &'a str) -> Option<Entity<'a>>

Create the mention result type. The concrete type varies by implementation.

fn mention_result( &self, s: &'a str, entity: Option<Pair<'a, Rule>>, ) -> Option<Entity<'a>>

Create a mention result type from a pest::Pair.

fn empty_result(&self) -> Vec<Entity<'a>>

Returns an empty result. Used when the input is invalid.

fn extract_impl(&self, s: &'a str, r_match: fn(Rule) -> bool) -> Self::T

fn extract_urls_with_indices(&self, s: &'a str) -> Self::T

Extract all URLs from the text, subject to value returned by Extract::get_extract_url_without_protocol.

fn extract_hashtags(&self, s: &'a str) -> Self::T

Extract all Hashtags from the text

fn extract_cashtags(&self, s: &'a str) -> Self::T

Extract all Cashtags from the text

fn extract_mentioned_screennames(&self, s: &'a str) -> Self::T

Extract all usernames from the text. The same as Extract::extract_mentioned_screennames_with_indices, but included for compatibility.

fn extract_mentioned_screennames_with_indices(&self, s: &'a str) -> Self::T

Extract all usernames from the text.

fn extract_mentions_or_lists_with_indices(&self, s: &'a str) -> Self::T

Extract all usernames and lists from the text.

fn extract_reply_username_impl(&self, s: &'a str) -> Self::Mention

Extract a “reply”–a username that appears at the beginning of a tweet.

fn extract_entities_with_indices(&self, s: &'a str) -> Self::T

Extract all entities from the text (Usernames, Lists, Hashtags, Cashtags, and URLs).

fn extract_scan(&self, s: &'a str) -> Self::T

Parse the text without extracting any entities.

fn entity_from_pair( &self, ue: UnprocessedEntity<'a>, start: i32, end: i32, ) -> Option<Entity<'a>>
