Variants

WHITESPACE

Matches whitespace characters including space, tab, and newline. This rule is used to ignore these characters in parsing, making the grammar more readable and flexible by disregarding non-essential spaces.

digit

Represents a single ASCII digit from 0 to 9. This rule allows us to match numeric characters in other rules where digits are required.

year

Matches a 4-digit year, e.g., “2024”. Used in date formats to specify the year component.

month

Matches a 2-digit month, e.g., “05” for May. Used in date formats to specify the month component.

day

Matches a 2-digit day, e.g., “12” for the 12th day of a month. Used in date formats to specify the day component.

date

Matches two date formats: “dd.mm.yyyy” or “mm/dd/yyyy”. Supports both European and American date formats for flexibility. Combines day, month, and year components separated by specific delimiters.

blockchain_name

Recognizes specific blockchain names: “SOL”, “BTC”, or “ETH”. This rule is used to identify and validate different blockchain types.

currency

Matches a specific set of currency codes: “USD”, “EUR”, or “UAH”. Used in financial fields to denote the currency associated with a numeric value.

number

Represents a formatted numeric value with optional commas for thousands separation and an optional decimal part. Examples include “1,000.50” or “200,200,200”. Allows flexibility in representing numeric data in financial contexts.

number_and_currency

Matches a number followed by a currency. Specifies the format for fields that require both a numeric amount and currency type.

entry

Defines the structure of an entire entry, combining all components in a specific format. An entry consists of name, date, open, close, high, low, and volume fields. Ensures consistency and proper format across all entries.

name

Matches a line that includes the blockchain name, formatted as “Name: <blockchain_name>;”. Ensures consistency in the format and captures the type of blockchain being referenced.

date_entry

, formatted as Matches a line containing the date“Date: ;“. Used to capture and verify the date component within an entry.

open

Matches the opening price line in the format “Open: <number_and_currency>;”. Specifies the format for the open price field in each entry.

close

Matches the closing price line in the format “Close: <number_and_currency>;”. Specifies the format for the close price field in each entry.

high

Matches the high price line in the format “High: <number_and_currency>;”. Specifies the format for the high price field in each entry.

low

Matches the low price line in the format “Low: <number_and_currency>;”. Specifies the format for the low price field in each entry.

volume

Matches the volume line in the format “Volume: <number_and_currency>;”. Specifies the format for the volume field, indicating the traded volume in a particular currency.

Implementations

impl Rule

pub fn all_rules() -> &'static [Rule]

Trait Implementations

impl Clone for Rule

fn clone(&self) -> Rule

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Rule

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

Formats the value using the given formatter.

impl Hash for Rule

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 Rule

fn cmp(&self, other: &Rule) -> 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 Parser<Rule> for BlockchainParser

fn parse<'i>(rule: Rule, input: &'i str) -> Result<Pairs<'i, Rule>, Error<Rule>>

Parses a &str starting from rule.

impl PartialEq for Rule

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

fn partial_cmp(&self, other: &Rule) -> 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.
