The GPUCompilationMessage interface of the WebGPU API represents a single informational, warning, or error message generated by the GPU shader module compiler.
An array of GPUCompilationMessage objects is available in the messages property of the GPUCompilationInfo object accessed via GPUShaderModule.getCompilationInfo().
length Experimental Read only
A number representing the length of the substring that the message corresponds to.
lineNum Experimental Read only
A number representing the line number in the shader code that the message corresponds to.
linePos Experimental Read only
A number representing the position in the code line that the message corresponds to. This could be an exact point, or the start of the relevant substring.
message Experimental Read only
A string representing human-readable message text.
offset Experimental Read only
A number representing the offset from the start of the shader code to the exact point, or the start of the relevant substring, that the message corresponds to.
type Experimental Read only
An enumerated value representing the type of the message — "error", "info", or "warning".
See the main GPUCompilationInfo page for an example.
