Struct ScanDatabaseHeader 

pub struct ScanDatabaseHeader {
    pub pattern_set_digest: [u8; 32],
    pub compiler_version: String,
    pub mode: ScanDatabaseMode,
    pub table_sections: Vec<ScanDatabaseSectionHeader>,
    pub unsupported_features: Vec<UnsupportedScanFeature>,
    pub compatibility: ScanDatabaseCompatibilityRecord,
}

Versioned, self-describing header for a serialized scan database.

Fields

pattern_set_digest: [u8; 32]

32-byte digest of the compiled pattern set.

compiler_version: String

Version string of the compiler that produced the database.

mode: ScanDatabaseMode

Scan mode the database was compiled for.

table_sections: Vec<ScanDatabaseSectionHeader>

Locators for the table sections in the database body.

unsupported_features: Vec<UnsupportedScanFeature>

Constructs that require verifier handoff.

compatibility: ScanDatabaseCompatibilityRecord

Construct-tier and dialect compatibility fingerprint.

Implementations

impl ScanDatabaseHeader

pub fn section_count(&self) -> usize

Number of table sections in the database body.

pub fn unsupported_feature_count(&self) -> usize

Number of unsupported-feature diagnostics recorded in the header.

pub fn validate_compatible( &self, expected_compiler_version: &str, expected_mode: ScanDatabaseMode, ) -> Result<(), String>

Validate this header against the consumer’s required compiler version and scan mode before any table payload is trusted.

Errors

Returns an actionable Fix: diagnostic when compiler version or mode differs from the expected cache key.

pub fn validate_database_compatibility( &self, expected_construct_tier_digest: u64, expected_dialect_digest: u64, accepted_reader_compatibility: &[ScanDatabaseReaderCompatibility], ) -> Result<(), String>

Validate construct-tier and dialect compatibility before trusting table payload bytes.

Errors

Returns a Fix: diagnostic when the construct-tier digest, dialect digest, or reader compatibility class is not accepted by the caller.
