MessagePackDecodeLimits

[Source]

Limits for the streaming decoder. Protects against denial-of-service attacks where a malicious payload claims enormous sizes for variable-length values or deeply nested containers.

The default constructor applies conservative limits: 1 MB for str/bin/ext data, 131,072 for array/map element counts, and 512 for container nesting depth. Use unlimited() to disable all limits, or override individual limits:

// Default conservative limits:
let limits = MessagePackDecodeLimits

// Custom limits:
let limits = MessagePackDecodeLimits(
  where max_str_len' = 4096)

// No limits:
let limits = MessagePackDecodeLimits.unlimited()
