	UncompressableContentTypes []string
	Level                      Level

	EstimateCompressibility          bool
	EstimateCompressibilityThreshold float64
}

Config represents common compression-related configuration.

func (*Config) HasValidCompressionLevel ¶ added in v0.45.0

func (c *Config) HasValidCompressionLevel() bool

func (*Config) NeedsCompression ¶

func (c *Config) NeedsCompression(obj *objectSDK.Object) bool
