PgMemoryContextOptions

Namespace: Ankus

Assembly: Ankus.Runtime.dll

Configures the native block sizes of a PostgreSQL AllocSet memory context.

public sealed class PgMemoryContextOptions

Sizes are validated when creating a context. Nonzero sizes must satisfy the target PostgreSQL server’s alignment requirements; the native bridge also validates version-specific size limits. Blocks need not be powers of two, and the minimum context size may exceed the initial block size.

PgMemoryContextOptions(nuint, nuint, nuint)

Configures the native block sizes of a PostgreSQL AllocSet memory context.

public PgMemoryContextOptions(nuint minimumContextSize = 0, nuint initialBlockSize = 8192, nuint maximumBlockSize = 8388608)

Parameters:

minimumContextSize — nuint

The retained first-block size, or zero to use the initial block size.

initialBlockSize — nuint

The first ordinary allocation block size.

maximumBlockSize — nuint

The largest ordinary allocation block size.
