Built-in types

Primitive types are the building blocks of Foxglove's supported message schemas.

Each field in a message schema has a type. This type can be another message schema, an enum, or one of the primitive types documented below:

boolean

Either true or false.

bytes

Raw binary data, represented as a Uint8Array in JavaScript.

enum

Number that serves as a key in a set of named constants.

float64

64-bit floating-point number.

string

String value encoded as UTF-8.

uint32

Non-negative integer value between 0 and 2³²−1.

int32

Integer value between −2³¹ and 2³¹−1.
