Struct EsePage 

pub struct EsePage {
    pub page_number: u32,
    pub data: Vec<u8>,
}

A single ESE database page.

Fields

page_number: u32

Page number (1-based).

data: Vec<u8>

Raw page data. Parse flags via EsePage::parse_header.

Implementations

impl EsePage

pub const HEADER_SIZE: usize = 40

Minimum size of the Vista+ page header.

pub fn parse_header(&self) -> Result<EsePageHeader, EseError>

Parse the Vista+ 40-byte page header from self.data.

Layout (all little-endian):

• 0x00 (4): XOR checksum
• 0x04 (4): ECC checksum (Vista+ addition)
• 0x08 (8): database time (JET_DBTIME)
• 0x10 (4): previous page number
• 0x14 (4): next page number
• 0x18 (4): FDP object ID
• 0x1C (2): available data size
• 0x1E (2): available uncommitted data
• 0x20 (2): available data offset
• 0x22 (2): available page tag count
• 0x24 (4): page flags

Errors

Returns EseError::Corrupt if self.data is shorter than 40 bytes.

pub fn tags(&self) -> Result<Vec<(u16, u16)>, EseError>

Return the tag entries from the end of the page.

Tags are stored at the END of the page, growing downward. Each tag is 4 bytes: bits 0-14 = value offset, bit 15 = flag, bits 16-30 = value size, bit 31 = flag.

Returns Vec<(offset, size)> for each tag.

Errors

Returns EseError::TagArrayOverflow if the page is too short to hold the declared tag count.

pub fn raw_data_area(&self) -> Result<&[u8], EseError>

Return the raw data area of the page: bytes from the end of the 40-byte page header to the start of the tag array at the page end.

This span contains ALL record bytes laid out sequentially, including bytes that may fall before the smallest tag offset (common in ESE’s cumulative key-prefix-compression format). Scanning this area directly (rather than individual tags) is the correct way to read real ESE catalog pages.

Errors

Returns EseError::Corrupt if the header cannot be parsed.

pub fn record_data(&self, index: usize) -> Result<&[u8], EseError>

Return the raw record data slice for tag at index.

Tag 0 is the page header tag. Data records start at tag 1.

Errors

Returns EseError::Corrupt if index is beyond the tag count, or EseError::RecordTooShort if the tag’s data range is out of bounds.
