Struct CollationCapabilities 

Source 
pub struct CollationCapabilities;
Expand description

Database collation capabilities.

Provides information about what collation features each database supports.

Implementations§

Source§

impl CollationCapabilities

Source

pub const fn supports_locale_collation(db_type: DatabaseType) -> bool

Check if database supports locale-specific collations.

  • PostgreSQL: ✅ Full support via ICU or libc
  • MySQL: ❌ Only charset-based collations
  • SQLite: ❌ Limited to NOCASE or custom functions
  • SQL Server: ✅ Language-specific collations
Source

pub const fn requires_custom_collation(db_type: DatabaseType) -> bool

Check if database requires custom collation registration.

SQLite requires custom collation functions to be registered for locale-aware sorting beyond NOCASE.

Source

pub const fn strategy(db_type: DatabaseType) -> &'static str

Get collation strategy description for database.

Source

pub const fn recommended_provider(db_type: DatabaseType) -> Option<&'static str>

Get recommended collation provider for database.
