Enum StaticFileSegment

pub enum StaticFileSegment {
    Headers,
    Transactions,
    Receipts,
}

Segment of the data that can be moved to static files.

Variants

Headers

Static File segment responsible for the CanonicalHeaders, Headers, HeaderTerminalDifficulties tables.

Transactions

Static File segment responsible for the Transactions table.

Receipts

Static File segment responsible for the Receipts table.

Implementations

impl StaticFileSegment

pub const fn as_str(&self) -> &'static str

Returns the segment as a string.

pub const fn config(&self) -> SegmentConfig

Returns the default configuration of the segment.

pub const fn columns(&self) -> usize

Returns the number of columns for the segment

pub fn filename(&self, block_range: &SegmentRangeInclusive) -> String

Returns the default file name for the provided segment and range.

pub fn filename_with_configuration( &self, compression: Compression, block_range: &SegmentRangeInclusive, ) -> String

Returns file name for the provided segment and range, alongside filters, compression.

pub fn parse_filename( name: &str, ) -> Option<(StaticFileSegment, SegmentRangeInclusive)>

Parses a filename into a StaticFileSegment and its expected block range.

The filename is expected to follow the format: “static_file{segment}{block_start}_{block_end}”. This function checks for the correct prefix (“static_file”), and then parses the segment and the inclusive ranges for blocks. It ensures that the start of each range is less than or equal to the end.

Returns

• Some((segment, block_range)) if parsing is successful and all conditions are met.
• None if any condition fails, such as an incorrect prefix, parsing error, or invalid range.

Note

This function is tightly coupled with the naming convention defined in Self::filename. Any changes in the filename format in filename should be reflected here.

pub const fn is_headers(&self) -> bool

Returns true if the segment is StaticFileSegment::Headers.

pub const fn is_receipts(&self) -> bool

Returns true if the segment is StaticFileSegment::Receipts.

pub const fn is_tx_based(&self) -> bool

Returns true if the segment is StaticFileSegment::Receipts or StaticFileSegment::Transactions.

impl Ord for StaticFileSegment

fn cmp(&self, other: &StaticFileSegment) -> Ordering

This method returns an Ordering between self and other.
