encode_to_buffer_unchecked()

void esphome::api::ProtoVarInt::encode_to_buffer_unchecked ( uint8_t * buffer, size_t len )

inline

Encode the varint value to a pre-allocated buffer without bounds checking.

Parameters

buffer	The pre-allocated buffer to write the encoded varint to
len	The size of the buffer in bytes

Note

The caller is responsible for ensuring the buffer is large enough to hold the encoded value. Use ProtoSize::varint() to calculate the exact size needed before calling this method.

No bounds checking is performed for performance reasons.
