Struct LedgerFile

pub struct LedgerFile {
    pub path: PathBuf,
    pub slot_number: SlotNumber,
    pub filename: String,
}

Represent an ledger file in a Cardano node database directory

Fields

path: PathBuf

The path to the ledger file

slot_number: SlotNumber

The ledger file slot number

filename: String

The filename

Implementations

impl LedgerFile

pub fn new<T: Into<String>>( path: PathBuf, slot_number: SlotNumber, filename: T, ) -> Self

LedgerFile factory

pub fn from_path(path: &Path) -> Option<LedgerFile>

Convert a path to a LedgerFile if it satisfies the LedgerFile constraints.

The constraints are: the path must be a file, the filename should only contain a number (no extension).

pub fn list_all_in_dir( dir: &Path, ) -> Result<Vec<LedgerFile>, LedgerFileListingError>

List all LedgerFile in a given directory.

Trait Implementations

impl Clone for LedgerFile

fn clone(&self) -> LedgerFile

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LedgerFile

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

Formats the value using the given formatter.

impl Ord for LedgerFile

fn cmp(&self, other: &Self) -> 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 PartialEq for LedgerFile

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

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