Implementations

impl ScreenerType

pub fn as_scr_id(&self) -> &'static str

Convert to Yahoo Finance scrId parameter value (SCREAMING_SNAKE_CASE)

pub fn parse(s: &str) -> Option<Self>

Parse from string, returns None on invalid input

Example

use finance_query::ScreenerType;

assert_eq!(ScreenerType::parse("most-actives"), Some(ScreenerType::MostActives));
assert_eq!(ScreenerType::parse("day-gainers"), Some(ScreenerType::DayGainers));

pub fn valid_types() -> &'static str

List all valid screener types for error messages

pub fn all() -> &'static [ScreenerType]

Get all screener types as an array

Trait Implementations

impl Clone for ScreenerType

fn clone(&self) -> ScreenerType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScreenerType

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

Formats the value using the given formatter.

impl FromStr for ScreenerType

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for ScreenerType

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 PartialEq for ScreenerType

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