Graph file validation utilities

Implementations

impl GraphFileValidator

pub fn validate_file_size( file_size: u64, persistent_header: &PersistentHeaderV2, ) -> NativeResult<()>

Validate that the file size meets minimum requirements

Ensures the file is large enough for the header and any declared data. For native backend, we only require file to be large enough for actual data written.

pub fn verify_commit_marker(marker: u64) -> NativeResult<()>

Verify the commit marker indicates a clean commit state

Detects incomplete clustered commits by checking the commit marker. Returns error if the marker indicates an incomplete transaction.

pub const fn clean_commit_marker() -> u64

Get the clean commit marker value

pub const fn commit_marker_offset() -> u64

Get the commit marker offset in the header

CRITICAL: Commit marker is positioned AFTER the header region (bytes 0-79) to prevent collision with header fields. The header occupies bytes 0-79 (HEADER_SIZE=80), so the commit marker is at offset 80, immediately following the header.

pub fn calculate_minimum_expected_size( persistent_header: &PersistentHeaderV2, ) -> u64

Calculate minimum expected file size based on header state
